-# Introduction
-
-Here's a book that'll help you program in Rust on the Game Boy Advance (GBA).
-
-It's a work in progress of course, but so is most of everything in Rust.
-
-## Style and Purpose
-
-I'm out to teach you how to program in Rust on the GBA, obviously. However,
-while there _is_ a [gba](https://github.com/rust-console/gba) crate, and while I
-genuinely believe it to be a good and useful crate for GBA programming, we _will
-not_ be using the `gba` crate within this book. In fact we won't be using any
-crates at all. We can call it the [Handmade Hero](https://handmadehero.org/)
-approach, if you like.
-
-I don't want to just teach you how to use the `gba` crate, I want to teach you
-what you'd need to know to write the crate from scratch if it wasn't there.
-
-Each chapter of the book will focus on a few things you'll need to know about
-GBA programming and then present a fully self-contained example that puts those
-ideas into action. Just one file per example, no dependencies, no external
-assets, no fuss. The examples will be in the text of the book within code
-blocks, but also you can find them in the [examples
-directory](https://github.com/rust-console/gba/tree/master/examples) of the repo
-if you want to get them that way.
-
-## Expected Knowledge
-
-I will try not to ask too much of the reader ahead of time, but you are expected
-to have already read [The Rust Book](https://doc.rust-lang.org/book/). Having
-also read through the [Rustonomicon](https://doc.rust-lang.org/nomicon/) is
-appreciated but not required.
-
-It's very difficult to know when you've said something that someone else won't
-already know about, or if you're presenting ideas out of order. If things aren't
-clear please [file an issue](https://github.com/rust-console/gba/issues) and
-we'll try to address it.
-
-## Getting Help
-
-If you want to contact us you should join the [Rust Community
-Discord](https://discordapp.com/invite/aVESxV8) and ask in the `#gamedev`
-channel.
-
-* `Ketsuban` is the wizard who knows much more about how it all works
-* `Lokathor` is the fool who decided to write a crate and book for it.
-
-If it's _not_ a GBA specific question then you can probably ask any of the other
-folks in the server as well (there's a few hundred folks).
-
-## Further Reading
-
-If you want to read more about developing on the GBA there are some other good
-resources as well:
-
-* [TONC](https://www.coranac.com/tonc/text/toc.htm), a tutorial series written
-  for C, but it's what I based the ordering of this book's sections on.
-* [GBATEK](http://problemkaputt.de/gbatek.htm), a homebrew tech manual for
-  GBA/NDS/DSi. We will regularly link to parts of it when talking about various
-  bits of the GBA.
-* [Getting Something for Nothing](https://www.youtube.com/watch?v=t99L3JHhLc0)
-  by James Munns. RustConf 2018. It specifically talks about zero cost
-  abstraction within an embedded rust context, which is exactly what we're all
-  about.

+# Introduction
+
+This is the book for learning how to write GBA games in Rust.
+
+I'm **Lokathor**, the main author of the book. There's also **Ketsuban** who
+provides the technical advisement, reviews the PRs, and keeps my crazy in check.
+
+The book is a work in progress, as you can see if you actually try to open many
+of the pages listed in the Table Of Contents.
+
+## Feedback
+
+It's also often hard to tell when you've explained something properly to someone
+who doesn't understand the concept yet. Please, if things don't make sense then
+[file an issue](https://github.com/rust-console/gba/issues) about it so I know
+where things need to improve.

+# Reader Requirements
+
+This book naturally assumes that you've already read Rust's core book:
+
+* [The Rust Programming Language](https://doc.rust-lang.org/book/)
+
+Now, I _know_ it sounds silly to say "if you wanna program Rust on this old
+video game system you should already know how to program Rust", but the more
+people I meet and chat with the more they tell me that they jumped into Rust
+without reading any or all of the book. You know who you are.
+
+Please, read the whole book!
+
+In addition to the core book, there's also an expansion book that I will declare
+to be required reading for this:
+
+* [The Rustonomicon](https://doc.rust-lang.org/nomicon/)
+
+The Rustonomicon is all about trying to demystify `unsafe`. We'll end up using a
+fair bit of unsafe code as a natural consequence of doing direct hardware
+manipulations. Using unsafe is like [swinging a
+sword](https://www.zeldadungeon.net/wp-content/uploads/2013/04/tumblr_mlkpzij6T81qizbpto1_1280.gif),
+you should start slowly, practice carefully, and always pay attention no matter
+how experienced you think you've become.
+
+That said, it's sometimes a [necessary
+tool](https://www.youtube.com/watch?v=rTo2u13lVcQ) to get the job done, so you
+have to break out of the borderline pathological fear of using it that most rust
+programmers tend to have.

+# Book Goals and Style
+
+So, what's this book actually gonna teach you?
+
+I'm _not_ gonna tell you how to use a crate that already exists.
+
+Don't get me wrong, there _is_ a [gba](https://crates.io/crates/gba) crate, and
+it's on crates.io and all that jazz.
+
+However, unlike most crates that come with a tutorial book, I don't want to just
+teach you how to use the crate. What I want is to teach you what you need to
+know so that you could build the crate yourself, from scratch, if it didn't
+already exist for you. Let's call it the [Handmade
+Hero](https://handmadehero.org/) school of design. Much more than you might find
+in other Rust crate books, I'll be attempting to show a lot of the _why_ in
+addition to just the _how_. Once you know how to do it all on your own, you can
+decide for yourself if the `gba` crate does it well, or if you think you can
+come up with something that suits your needs better.
+
+Overall the book is sorted for easy review once you're trying to program
+something, and the GBA has a few interconnected concepts, so some parts of the
+book end up having to refer you to portions that you haven't read yet. The
+chapters and sections are sorted so that _minimal_ future references are
+required, but it's unavoidable.
+
+The actual "tutorial order" of the book is the
+[Examples](../05-examples/00-index.md) chapter. Each section of that chapter
+breaks down one of the provided examples in the [examples
+directory](https://github.com/rust-console/gba/tree/master/examples) of the
+repository. We go over what sections of the book you'll need to have read for
+the example code to make sense, and also how we apply the general concepts
+described in the book to the specific example cases.

+# Hello, Magic
+
+So we know all the steps to build our source, we just need some source.
+
+We're beginners, so we'll start small. With normal programming there's usually a
+console available, so the minimal program prints "Hello, world" to the terminal.
+On a GBA we don't have a terminal and standard out and all that, so the minimal
+program draws a red, blue, and green dot to the screen.
+
+At the lowest level of device programming, it's all [Magic
+Numbers](https://en.wikipedia.org/wiki/Magic_number_(programming)). You write
+special values to special places and then the hardware does something. A clear
+API makes every magic number and magic location easy to understand. A clear _and
+good_ API also prevents you from using the wrong magic number in the wrong place
+and causing problems for yourself.
+
+This is the minimal example to just test that our build system is all set, so
+just this once we'll go _full_ magic number crazy town, for fun. Ready? Here
+goes:
+
+`hello_magic.rs`:
+
+```rust
+#![feature(start)]
+#![no_std]
+
+#[panic_handler]
+fn panic(_info: &core::panic::PanicInfo) -> ! {

+# Newtype
+
+There's one thing I want to get out of the way near the start of the book and it
+didn't really have a good fit anywhere else in the book so it goes right here.
+
+We're talking about the "Newtype Pattern"!
+
+Now, I told you to read the Rust Book before you read this book, and I'm sure
+you're all good students who wouldn't sneak into this book without doing the
+required reading, so I'm sure you all remember exactly what I'm talking about,
+because they touch on the newtype concept in the book twice, in two _very_ long
+named sections:
+
+* [Using the Newtype Pattern to Implement External Traits on External
+  Types](https://doc.rust-lang.org/book/ch19-03-advanced-traits.html#using-the-newtype-pattern-to-implement-external-traits-on-external-types)
+* [Using the Newtype Pattern for Type Safety and
+  Abstraction](https://doc.rust-lang.org/book/ch19-04-advanced-types.html#using-the-newtype-pattern-for-type-safety-and-abstraction)
+
+...Yeah... The Rust Book doesn't know how to make a short sub-section name to
+save its life. Shame.
+
+## Newtype Basics
+
+So, we have all these pieces of data, and we want to keep them separated, and we
+don't wanna pay the cost for it at runtime. Well, we're in luck, we can pay the
+cost at compile time.
+
+```rust
+pub struct PixelColor(u16);
+```
+
+Ah, except that, as I'm sure you remember from [The
+Rustonomicon](https://doc.rust-lang.org/nomicon/other-reprs.html#reprtransparent)
+(and from [the
+RFC](https://github.com/rust-lang/rfcs/blob/master/text/1758-repr-transparent.md)
+too, of course), if we have a single field struct that's sometimes different
+from having just the bare value, so we should be using `#[repr(transparent)]`
+with our newtypes.
+
+```rust
+#[repr(transparent)]
+pub struct PixelColor(u16);
+```
+
+Ah, and of course we'll need to make it so you can unwrap the value:
+
+```rust
+#[repr(transparent)]
+pub struct PixelColor(u16);
+
+impl From<PixelColor> for u16 {
+  fn from(color: PixelColor) -> u16 {
+    color.0
+  }
+}
+```
+
+And then we'll need to do that same thing for _every other newtype we want_.
+
+Except there's only two tiny parts that actually differ between newtype
+declarations: the new name and the base type. All the rest is just the same rote
+code over and over. Generating piles and piles of boilerplate code? Sounds like
+a job for a macro to me!
+
+## Making It A Macro
+
+The most basic version of the macro we want goes like this:
+
+```rust
+#[macro_export]
+macro_rules! newtype {
+  ($new_name:ident, $old_name:ident) => {
+    #[repr(transparent)]
+    pub struct $new_name($old_name);
+  };
+}
+```
+
+Except we also want to be able to add attributes (which includes doc comments),
+so we upgrade our macro a bit:
+
+```rust
+#[macro_export]
+macro_rules! newtype {
+  ($(#[$attr:meta])* $new_name:ident, $old_name:ident) => {
+    $(#[$attr])*
+    #[repr(transparent)]
+    pub struct $new_name($old_name);
+  };
+}
+```
+
+And we want to automatically add the ability to turn the wrapper type back into
+the wrapped type.
+
+```rust
+#[macro_export]
+macro_rules! newtype {
+  ($(#[$attr:meta])* $new_name:ident, $old_name:ident) => {
+    $(#[$attr])*
+    #[repr(transparent)]
+    pub struct $new_name($old_name);
+    
+    impl From<$new_name> for $old_name {
+      fn from(x: $new_name) -> $old_name {
+        x.0
+      }
+    }
+  };
+}
+```
+
+That seems like enough for all of our examples, so we'll stop there. We could
+add more things, such as making the `From` impl optional (because what if you
+shouldn't unwrap it for some weird reason?), allowing for more precise
+visibility controls (on both the newtype overall and the inner field), and maybe
+even other things I can't think of right now. We won't really need those in our
+example code for this book, so it's probably nicer to just keep the macro
+simpler and quit while we're ahead.
+
+**As a reminder:** remember that macros have to appear _before_ they're invoked in
+your source, so the `newtype` macro will always have to be at the very top of
+your file, or in a module that's declared before other modules and code.

+# Help and Resources
+
+## Help
+
+So you're stuck on a problem and the book doesn't say what to do. Where can you
+find out more?
+
+The first place I would suggest is the [Rust Community
+Discord](https://discordapp.com/invite/aVESxV8). If it's a general Rust question
+then you can ask anyone in any channel you feel is appropriate. If it's GBA
+specific then you can try asking me (`Lokathor`) or `Ketsuban` in the `#gamedev`
+channel.
+
+## Emulators
+
+You certainly might want to eventually write a game that you can put on a flash
+cart and play on real hardware, but for most of your development you'll probably
+want to be using an emulator for testing, because you don't have to fiddle with
+cables and all that.
+
+In terms of emulators, you want to be using
+[mGBA](https://github.com/mgba-emu/mgba), and you want to be using the [0.7 Beta
+1](https://github.com/mgba-emu/mgba/releases/tag/0.7-b1) or later. This update
+lets you run raw ELF files, which means that you can have full debug symbols
+available while you're debugging problems.
+
+## Information Resources
+
+Ketsuban and I didn't magically learn this all from nowhere, we read various
+technical manuals and guides ourselves and then distilled the knowledge (usually
+oriented towards C and C++) into this book for Rust.
+
+We have personally used some or all of the following:
+
+* [GBATEK](http://problemkaputt.de/gbatek.htm): This is _the_ resource. It
+  covers not only the GBA, but also the DS and DSi, and also a run down of ARM
+  assembly (32-bit and 16-bit opcodes). The link there is to the 2.9b version on
+  `problemkaputt.de` (the official home of the document), but if you just google
+  for gbatek the top result is for the 2.5 version on `akkit.org`, so make sure
+  you're looking at the newest version. Sometimes `problemkaputt.de` is a little
+  sluggish so I've also [mirrored](https://lokathor.com/gbatek.html) the 2.9b
+  version on my own site as well. GBATEK is rather large, over 2mb of text, so
+  if you're on a phone or similar you might want to save an offline copy to go
+  easy on your data usage.
+* [TONC](https://www.coranac.com/tonc/text/): While GBATEK is basically just a
+  huge tech specification, TONC is an actual _guide_ on how to make sense of the
+  GBA's abilities and organize it into a game. It's written for C of course, but
+  it's a large
+* [CowBite](https://www.cs.rit.edu/~tjh8300/CowBite/CowBiteSpec.htm): This is
+  more like GBATEK, and it's less complete, but it mixes in a little more
+  friendly explanation of things in between the hardware spec parts.
+
+And I haven't had time to look at it myself, [The Audio
+Advance](http://belogic.com/gba/) seems to be very good. It explains in depth
+how you can get audio working on the GBA. Note that the table of contents for
+each page goes along the top instead of down the side.
+
+## Non-Rust GBA Community
+
+There's also the [GBADev.org](http://www.gbadev.org/) site, which has a forum
+and everything. They're coding in C and C++, but you can probably overcome that
+difference with a little work on your part.
+
+I also found a place called
+[GBATemp](https://gbatemp.net/categories/nintendo-gba-discussions.32/), which
+seems to have a more active forum but less of a focus on actual coding.

+<p>This book naturally assumes that you've already read Rust's core book:</p>
+<ul>
+<li><a href="https://doc.rust-lang.org/book/">The Rust Programming Language</a></li>
+</ul>
+<p>Now, I <em>know</em> it sounds silly to say &quot;if you wanna program Rust on this old
+video game system you should already know how to program Rust&quot;, but the more
+people I meet and chat with the more they tell me that they jumped into Rust
+without reading any or all of the book. You know who you are.</p>
+<p>Please, read the whole book!</p>
+<p>In addition to the core book, there's also an expansion book that I will declare
+to be required reading for this:</p>
+<ul>
+<li><a href="https://doc.rust-lang.org/nomicon/">The Rustonomicon</a></li>
+</ul>
+<p>The Rustonomicon is all about trying to demystify <code>unsafe</code>. We'll end up using a
+fair bit of unsafe code as a natural consequence of doing direct hardware
+manipulations. Using unsafe is like <a href="https://www.zeldadungeon.net/wp-content/uploads/2013/04/tumblr_mlkpzij6T81qizbpto1_1280.gif">swinging a
+sword</a>,
+you should start slowly, practice carefully, and always pay attention no matter
+how experienced you think you've become.</p>
+<p>That said, it's sometimes a <a href="https://www.youtube.com/watch?v=rTo2u13lVcQ">necessary
+tool</a> to get the job done, so you
+have to break out of the borderline pathological fear of using it that most rust
+programmers tend to have.</p>

+<p>So, what's this book actually gonna teach you?</p>
+<p>I'm <em>not</em> gonna tell you how to use a crate that already exists.</p>
+<p>Don't get me wrong, there <em>is</em> a <a href="https://crates.io/crates/gba">gba</a> crate, and
+it's on crates.io and all that jazz.</p>
+<p>However, unlike most crates that come with a tutorial book, I don't want to just
+teach you how to use the crate. What I want is to teach you what you need to
+know so that you could build the crate yourself, from scratch, if it didn't
+already exist for you. Let's call it the <a href="https://handmadehero.org/">Handmade
+Hero</a> school of design. Much more than you might find
+in other Rust crate books, I'll be attempting to show a lot of the <em>why</em> in
+addition to just the <em>how</em>. Once you know how to do it all on your own, you can
+decide for yourself if the <code>gba</code> crate does it well, or if you think you can
+come up with something that suits your needs better.</p>
+<p>Overall the book is sorted for easy review once you're trying to program
+something, and the GBA has a few interconnected concepts, so some parts of the
+book end up having to refer you to portions that you haven't read yet. The
+chapters and sections are sorted so that <em>minimal</em> future references are
+required, but it's unavoidable.</p>
+<p>The actual &quot;tutorial order&quot; of the book is the
+<a href="../05-examples/00-index.html">Examples</a> chapter. Each section of that chapter
+breaks down one of the provided examples in the <a href="https://github.com/rust-console/gba/tree/master/examples">examples

+                        <a class="header" href="#development-setup" id="development-setup"><h1>Development Setup</h1></a>
+<p>Before you can build a GBA game you'll have to follow some special steps to
+setup the development environment.</p>
+<p>Once again, extra special thanks to <strong>Ketsuban</strong>, who first dove into how to
+make this all work with rust and then shared it with the world.</p>
+<a class="header" href="#per-system-setup" id="per-system-setup"><h2>Per System Setup</h2></a>
+<p>Obviously you need your computer to have a <a href="https://rustup.rs/">working rust
+installation</a>. However, you'll also need to ensure that
+you're using a nightly toolchain (we will need it for inline assembly, among
+other potential useful features). You can run <code>rustup default nightly</code> to set
+nightly as the system wide default toolchain, or you can use a <a href="https://github.com/rust-lang-nursery/rustup.rs#the-toolchain-file">toolchain
+file</a> to use
+nightly just on a specific project, but either way we'll be assuming the use of
+nightly from now on. You'll also need the <code>rust-src</code> component so that
+<code>cargo-xbuild</code> will be able to compile the core crate for us in a bit, so run
+<code>rustup component add rust-src</code>.</p>
+<p>Next, you need <a href="https://devkitpro.org/wiki/Getting_Started">devkitpro</a>. They've
+got a graphical installer for Windows that runs nicely, and I guess <code>pacman</code>
+support on Linux (I'm on Windows so I haven't tried the Linux install myself).
+We'll be using a few of their general binutils for the <code>arm-none-eabi</code> target,
+and we'll also be using some of their tools that are specific to GBA
+development, so <em>even if</em> you already have the right binutils for whatever
+reason, you'll still want devkitpro for the <code>gbafix</code> utility.</p>
+<ul>
+<li>On Windows you'll want something like <code>C:\devkitpro\devkitARM\bin</code> and
+<code>C:\devkitpro\tools\bin</code> to be <a href="https://stackoverflow.com/q/44272416/455232">added to your
+PATH</a>, depending on where you
+installed it to and such.</li>
+<li>On Linux you can use pacman to get it, and the default install puts the stuff
+in <code>/opt/devkitpro/devkitARM/bin</code> and <code>/opt/devkitpro/tools/bin</code>. If you need
+help you can look in our repository's
+<a href="https://github.com/rust-console/gba/blob/master/.travis.yml">.travis.yml</a>
+file to see exactly what our CI does.</li>
+</ul>
+<p>Finally, you'll need <code>cargo-xbuild</code>. Just run <code>cargo install cargo-xbuild</code> and
+cargo will figure it all out for you.</p>
+<a class="header" href="#per-project-setup" id="per-project-setup"><h2>Per Project Setup</h2></a>
+<p>Once the system wide tools are ready, you'll need some particular files each
+time you want to start a new project. You can find them in the root of the
+<a href="https://github.com/rust-console/gba">rust-console/gba repo</a>.</p>
+<ul>
+<li><code>thumbv4-none-agb.json</code> describes the overall GBA to cargo-xbuild (and LLVM)
+so it knows what to do. Technically the GBA is <code>thumbv4-none-eabi</code>, but we
+change the <code>eabi</code> to <code>agb</code> so that we can distinguish it from other <code>eabi</code>
+devices when using <code>cfg</code> flags.</li>
+<li><code>crt0.s</code> describes some ASM startup stuff. If you have more ASM to place here
+later on this is where you can put it. You also need to build it into a
+<code>crt0.o</code> file before it can actually be used, but we'll cover that below.</li>
+<li><code>linker.ld</code> tells the linker all the critical info about the layout
+expectations that the GBA has about our program, and that it should also
+include the <code>crt0.o</code> file with our compiled rust code.</li>
+</ul>
+<a class="header" href="#compiling" id="compiling"><h2>Compiling</h2></a>
+<p>Once all the tools are in place, there's particular steps that you need to
+compile the project. For these to work you'll need some source code to compile.
+Unlike with other things, an empty main file and/or an empty lib file will cause
+a total build failure, because we'll need a
+<a href="https://rust-embedded.github.io/book/intro/no-std.html">no_std</a> build, and rust
+defaults to builds that use the standard library. The next section has a minimal
+example file you can use (along with explanation), but we'll describe the build
+steps here.</p>
+<ul>
+<li>
+<p><code>arm-none-eabi-as crt0.s -o target/crt0.o</code></p>
+<ul>
+<li>This builds your text format <code>crt0.s</code> file into object format <code>crt0.o</code>
+that's placed in the <code>target/</code> directory. Note that if the <code>target/</code>
+directory doesn't exist yet it will fail, so you have to make the directory
+if it's not there. You don't need to rebuild <code>crt0.s</code> every single time,
+only when it changes, but you might as well throw a line to do it every time
+into your build script so that you never forget because it's a practically
+instant operation anyway.</li>
+</ul>
+</li>
+<li>
+<p><code>cargo xbuild --target thumbv4-none-agb.json</code></p>
+<ul>
+<li>This builds your Rust source. It accepts <em>most of</em> the normal options, such
+as <code>--release</code>, and options, such as <code>--bin foo</code> or <code>--examples</code>, that you'd
+expect <code>cargo</code> to accept.</li>
+<li>You <strong>can not</strong> build and run tests this way, because they require <code>std</code>,
+which the GBA doesn't have. If you want you can still run some of your
+project's tests with <code>cargo test --lib</code> or similar, but that builds for your
+local machine, so anything specific to the GBA (such as reading and writing
+registers) won't be testable that way. If you want to isolate and try out
+some piece code running on the GBA you'll unfortunately have to make a demo
+for it in your <code>examples/</code> directory and then run the demo in an emulator
+and see if it does what you expect.</li>
+<li>The file extension is important! It will work if you forget it, but <code>cargo xbuild</code> takes the inclusion of the extension as a flag to also compile
+dependencies with the same sysroot, so you can include other crates in your
+build. Well, creates that work in the GBA's limited environment, but you get
+the idea.</li>
+</ul>
+</li>
+</ul>
+<p>At this point you have an ELF binary that some emulators can execute directly
+(more on that later). However, if you want a &quot;real&quot; ROM that works in all
+emulators and that you could transfer to a flash cart to play on real hardware
+there's a little more to do.</p>
+<ul>
+<li>
+<p><code>arm-none-eabi-objcopy -O binary target/thumbv4-none-agb/MODE/BIN_NAME target/ROM_NAME.gba</code></p>
+<ul>
+<li>This will perform an <a href="https://linux.die.net/man/1/objcopy">objcopy</a> on our
+program. Here I've named the program <code>arm-none-eabi-objcopy</code>, which is what
+devkitpro calls their version of <code>objcopy</code> that's specific to the GBA in the
+Windows install. If the program isn't found under that name, have a look in
+your installation directory to see if it's under a slightly different name
+or something.</li>
+<li>As you can see from reading the man page, the <code>-O binary</code> option takes our
+lovely ELF file with symbols and all that and strips it down to basically a
+bare memory dump of the program.</li>
+<li>The next argument is the input file. You might not be familiar with how
+<code>cargo</code> arranges stuff in the <code>target/</code> directory, and between RLS and
+<code>cargo doc</code> and stuff it gets kinda crowded, so it goes like this:
+<ul>
+<li>Since our program was built for a non-local target, first we've got a
+directory named for that target, <code>thumbv4-none-agb/</code></li>
+<li>Next, the &quot;MODE&quot; is either <code>debug/</code> or <code>release/</code>, depending on if we had
+the <code>--release</code> flag included. You'll probably only be packing release
+mode programs all the way into GBA roms, but it works with either mode.</li>
+<li>Finally, the name of the program. If your program is something out of the
+project's <code>src/bin/</code> then it'll be that file's name, or whatever name you
+configured for the bin in the <code>Cargo.toml</code> file. If your program is
+something out of the project's <code>examples/</code> directory there will be a
+similar <code>examples/</code> sub-directory first, and then the example's name.</li>
+</ul>
+</li>
+<li>The final argument is the output of the <code>objcopy</code>, which I suggest putting
+at just the top level of the <code>target/</code> directory. Really it could go
+anywhere, but if you're using git then it's likely that your <code>.gitignore</code>
+file is already setup to exclude everything in <code>target/</code>, so this makes sure
+that your intermediate game builds don't get checked into your git.</li>
+</ul>
+</li>
+<li>
+<p><code>gbafix target/ROM_NAME.gba</code></p>
+<ul>
+<li>The <code>gbafix</code> tool also comes from devkitpro. The GBA is very picky about a
+ROM's format, and <code>gbafix</code> patches the ROM's header and such so that it'll
+work right. Unlike <code>objcopy</code>, this tool is custom built for GBA development,
+so it works just perfectly without any arguments beyond the file name. The
+ROM is patched in place, so we don't even need to specify a new destination.</li>
+</ul>
+</li>
+</ul>
+<p>And you're <em>finally</em> done!</p>
+<p>Of course, you probably want to make a script for all that, but it's up to you.
+On our own project we have it mostly set up within a <code>Makefile.toml</code> which runs
+using the <a href="https://github.com/sagiegurari/cargo-make">cargo-make</a> plugin.</p>

+<p>So we know all the steps to build our source, we just need some source.</p>
+<p>We're beginners, so we'll start small. With normal programming there's usually a
+console available, so the minimal program prints &quot;Hello, world&quot; to the terminal.
+On a GBA we don't have a terminal and standard out and all that, so the minimal
+program draws a red, blue, and green dot to the screen.</p>
+<p>At the lowest level of device programming, it's all <a href="https://en.wikipedia.org/wiki/Magic_number_(programming)">Magic
+Numbers</a>. You write
+special values to special places and then the hardware does something. A clear
+API makes every magic number and magic location easy to understand. A clear <em>and
+good</em> API also prevents you from using the wrong magic number in the wrong place
+and causing problems for yourself.</p>

+<p>Throw that into your project skeleton, build the program, and give it a run. You
+should see a red, green, and blue dot close-ish to the middle of the screen. If
+you don't, something <em>already</em> went wrong. Double check things, phone a friend,
+write your senators, try asking <code>Lokathor</code> or <code>Ketsuban</code> on the <a href="https://discordapp.com/invite/aVESxV8">Rust Community
+Discord</a>, until you're eventually able to
+get your three dots going.</p>
+<p>Of course, I'm sure you want to know why those numbers are the numbers to use.
+Well that's what the whole rest of the book is about!</p>

+<p>There's one thing I want to get out of the way near the start of the book and it
+didn't really have a good fit anywhere else in the book so it goes right here.</p>
+<p>We're talking about the &quot;Newtype Pattern&quot;!</p>
+<p>Now, I told you to read the Rust Book before you read this book, and I'm sure
+you're all good students who wouldn't sneak into this book without doing the
+required reading, so I'm sure you all remember exactly what I'm talking about,
+because they touch on the newtype concept in the book twice, in two <em>very</em> long
+named sections:</p>
+<ul>
+<li><a href="https://doc.rust-lang.org/book/ch19-03-advanced-traits.html#using-the-newtype-pattern-to-implement-external-traits-on-external-types">Using the Newtype Pattern to Implement External Traits on External
+Types</a></li>
+<li><a href="https://doc.rust-lang.org/book/ch19-04-advanced-types.html#using-the-newtype-pattern-for-type-safety-and-abstraction">Using the Newtype Pattern for Type Safety and
+Abstraction</a></li>
+</ul>
+<p>...Yeah... The Rust Book doesn't know how to make a short sub-section name to
+save its life. Shame.</p>
+<a class="header" href="#newtype-basics" id="newtype-basics"><h2>Newtype Basics</h2></a>
+<p>So, we have all these pieces of data, and we want to keep them separated, and we
+don't wanna pay the cost for it at runtime. Well, we're in luck, we can pay the
+cost at compile time.</p>
+<pre><pre class="playpen"><code class="language-rust">
+# #![allow(unused_variables)]
+#fn main() {
+pub struct PixelColor(u16);
+#}</code></pre></pre>
+<p>Ah, except that, as I'm sure you remember from <a href="https://doc.rust-lang.org/nomicon/other-reprs.html#reprtransparent">The
+Rustonomicon</a>
+(and from <a href="https://github.com/rust-lang/rfcs/blob/master/text/1758-repr-transparent.md">the
+RFC</a>
+too, of course), if we have a single field struct that's sometimes different
+from having just the bare value, so we should be using <code>#[repr(transparent)]</code>
+with our newtypes.</p>
+<pre><pre class="playpen"><code class="language-rust">
+# #![allow(unused_variables)]
+#fn main() {
+#[repr(transparent)]
+pub struct PixelColor(u16);
+#}</code></pre></pre>
+<p>Ah, and of course we'll need to make it so you can unwrap the value:</p>
+<pre><pre class="playpen"><code class="language-rust">
+# #![allow(unused_variables)]
+#fn main() {
+#[repr(transparent)]
+pub struct PixelColor(u16);
+
+impl From&lt;PixelColor&gt; for u16 {
+  fn from(color: PixelColor) -&gt; u16 {
+    color.0
+  }
+}
+#}</code></pre></pre>
+<p>And then we'll need to do that same thing for <em>every other newtype we want</em>.</p>
+<p>Except there's only two tiny parts that actually differ between newtype
+declarations: the new name and the base type. All the rest is just the same rote
+code over and over. Generating piles and piles of boilerplate code? Sounds like
+a job for a macro to me!</p>
+<a class="header" href="#making-it-a-macro" id="making-it-a-macro"><h2>Making It A Macro</h2></a>
+<p>The most basic version of the macro we want goes like this:</p>
+<pre><pre class="playpen"><code class="language-rust">
+# #![allow(unused_variables)]
+#fn main() {
+#[macro_export]
+macro_rules! newtype {
+  ($new_name:ident, $old_name:ident) =&gt; {
+    #[repr(transparent)]
+    pub struct $new_name($old_name);
+  };
+}
+#}</code></pre></pre>
+<p>Except we also want to be able to add attributes (which includes doc comments),
+so we upgrade our macro a bit:</p>
+<pre><pre class="playpen"><code class="language-rust">
+# #![allow(unused_variables)]
+#fn main() {
+#[macro_export]
+macro_rules! newtype {
+  ($(#[$attr:meta])* $new_name:ident, $old_name:ident) =&gt; {
+    $(#[$attr])*
+    #[repr(transparent)]
+    pub struct $new_name($old_name);
+  };
+}
+#}</code></pre></pre>
+<p>And we want to automatically add the ability to turn the wrapper type back into
+the wrapped type.</p>
+<pre><pre class="playpen"><code class="language-rust">
+# #![allow(unused_variables)]
+#fn main() {
+#[macro_export]
+macro_rules! newtype {
+  ($(#[$attr:meta])* $new_name:ident, $old_name:ident) =&gt; {
+    $(#[$attr])*
+    #[repr(transparent)]
+    pub struct $new_name($old_name);
+    
+    impl From&lt;$new_name&gt; for $old_name {
+      fn from(x: $new_name) -&gt; $old_name {
+        x.0
+      }
+    }
+  };
+}
+#}</code></pre></pre>
+<p>That seems like enough for all of our examples, so we'll stop there. We could
+add more things, such as making the <code>From</code> impl optional (because what if you
+shouldn't unwrap it for some weird reason?), allowing for more precise
+visibility controls (on both the newtype overall and the inner field), and maybe
+even other things I can't think of right now. We won't really need those in our
+example code for this book, so it's probably nicer to just keep the macro
+simpler and quit while we're ahead.</p>
+<p><strong>As a reminder:</strong> remember that macros have to appear <em>before</em> they're invoked in
+your source, so the <code>newtype</code> macro will always have to be at the very top of
+your file, or in a module that's declared before other modules and code.</p>

+<p>So you're stuck on a problem and the book doesn't say what to do. Where can you
+find out more?</p>
+<p>The first place I would suggest is the <a href="https://discordapp.com/invite/aVESxV8">Rust Community
+Discord</a>. If it's a general Rust question
+then you can ask anyone in any channel you feel is appropriate. If it's GBA
+specific then you can try asking me (<code>Lokathor</code>) or <code>Ketsuban</code> in the <code>#gamedev</code>
+channel.</p>
+<a class="header" href="#emulators" id="emulators"><h2>Emulators</h2></a>
+<p>You certainly might want to eventually write a game that you can put on a flash
+cart and play on real hardware, but for most of your development you'll probably
+want to be using an emulator for testing, because you don't have to fiddle with
+cables and all that.</p>
+<p>In terms of emulators, you want to be using
+<a href="https://github.com/mgba-emu/mgba">mGBA</a>, and you want to be using the <a href="https://github.com/mgba-emu/mgba/releases/tag/0.7-b1">0.7 Beta
+1</a> or later. This update
+lets you run raw ELF files, which means that you can have full debug symbols
+available while you're debugging problems.</p>
+<a class="header" href="#information-resources" id="information-resources"><h2>Information Resources</h2></a>
+<p>Ketsuban and I didn't magically learn this all from nowhere, we read various
+technical manuals and guides ourselves and then distilled the knowledge (usually
+oriented towards C and C++) into this book for Rust.</p>
+<p>We have personally used some or all of the following:</p>

+<li><a href="http://problemkaputt.de/gbatek.htm">GBATEK</a>: This is <em>the</em> resource. It

+<code>problemkaputt.de</code> (the official home of the document), but if you just google
+for gbatek the top result is for the 2.5 version on <code>akkit.org</code>, so make sure
+you're looking at the newest version. Sometimes <code>problemkaputt.de</code> is a little
+sluggish so I've also <a href="https://lokathor.com/gbatek.html">mirrored</a> the 2.9b
+version on my own site as well. GBATEK is rather large, over 2mb of text, so
+if you're on a phone or similar you might want to save an offline copy to go
+easy on your data usage.</li>
+<li><a href="https://www.coranac.com/tonc/text/">TONC</a>: While GBATEK is basically just a
+huge tech specification, TONC is an actual <em>guide</em> on how to make sense of the
+GBA's abilities and organize it into a game. It's written for C of course, but
+it's a large</li>
+<li><a href="https://www.cs.rit.edu/%7Etjh8300/CowBite/CowBiteSpec.htm">CowBite</a>: This is
+more like GBATEK, and it's less complete, but it mixes in a little more
+friendly explanation of things in between the hardware spec parts.</li>
+</ul>
+<p>And I haven't had time to look at it myself, <a href="http://belogic.com/gba/">The Audio
+Advance</a> seems to be very good. It explains in depth
+how you can get audio working on the GBA. Note that the table of contents for
+each page goes along the top instead of down the side.</p>
+<a class="header" href="#non-rust-gba-community" id="non-rust-gba-community"><h2>Non-Rust GBA Community</h2></a>
+<p>There's also the <a href="http://www.gbadev.org/">GBADev.org</a> site, which has a forum
+and everything. They're coding in C and C++, but you can probably overcome that
+difference with a little work on your part.</p>
+<p>I also found a place called
+<a href="https://gbatemp.net/categories/nintendo-gba-discussions.32/">GBATemp</a>, which
+seems to have a more active forum but less of a focus on actual coding.</p>

+<p>This is the book for learning how to write GBA games in Rust.</p>
+<p>I'm <strong>Lokathor</strong>, the main author of the book. There's also <strong>Ketsuban</strong> who
+provides the technical advisement, reviews the PRs, and keeps my crazy in check.</p>
+<p>The book is a work in progress, as you can see if you actually try to open many
+of the pages listed in the Table Of Contents.</p>
+<a class="header" href="#feedback" id="feedback"><h2>Feedback</h2></a>
+<p>It's also often hard to tell when you've explained something properly to someone
+who doesn't understand the concept yet. Please, if things don't make sense then
+<a href="https://github.com/rust-console/gba/issues">file an issue</a> about it so I know
+where things need to improve.</p>
 <a class="header" href="#reader-requirements" id="reader-requirements"><h1>Reader Requirements</h1></a>
+<p>This book naturally assumes that you've already read Rust's core book:</p>
+<ul>
+<li><a href="https://doc.rust-lang.org/book/">The Rust Programming Language</a></li>
+</ul>
+<p>Now, I <em>know</em> it sounds silly to say &quot;if you wanna program Rust on this old
+video game system you should already know how to program Rust&quot;, but the more
+people I meet and chat with the more they tell me that they jumped into Rust
+without reading any or all of the book. You know who you are.</p>
+<p>Please, read the whole book!</p>
+<p>In addition to the core book, there's also an expansion book that I will declare
+to be required reading for this:</p>
+<ul>
+<li><a href="https://doc.rust-lang.org/nomicon/">The Rustonomicon</a></li>
+</ul>
+<p>The Rustonomicon is all about trying to demystify <code>unsafe</code>. We'll end up using a
+fair bit of unsafe code as a natural consequence of doing direct hardware
+manipulations. Using unsafe is like <a href="https://www.zeldadungeon.net/wp-content/uploads/2013/04/tumblr_mlkpzij6T81qizbpto1_1280.gif">swinging a
+sword</a>,
+you should start slowly, practice carefully, and always pay attention no matter
+how experienced you think you've become.</p>
+<p>That said, it's sometimes a <a href="https://www.youtube.com/watch?v=rTo2u13lVcQ">necessary
+tool</a> to get the job done, so you
+have to break out of the borderline pathological fear of using it that most rust
+programmers tend to have.</p>

+<p>So, what's this book actually gonna teach you?</p>
+<p>I'm <em>not</em> gonna tell you how to use a crate that already exists.</p>
+<p>Don't get me wrong, there <em>is</em> a <a href="https://crates.io/crates/gba">gba</a> crate, and
+it's on crates.io and all that jazz.</p>
+<p>However, unlike most crates that come with a tutorial book, I don't want to just
+teach you how to use the crate. What I want is to teach you what you need to
+know so that you could build the crate yourself, from scratch, if it didn't
+already exist for you. Let's call it the <a href="https://handmadehero.org/">Handmade
+Hero</a> school of design. Much more than you might find
+in other Rust crate books, I'll be attempting to show a lot of the <em>why</em> in
+addition to just the <em>how</em>. Once you know how to do it all on your own, you can
+decide for yourself if the <code>gba</code> crate does it well, or if you think you can
+come up with something that suits your needs better.</p>
+<p>Overall the book is sorted for easy review once you're trying to program
+something, and the GBA has a few interconnected concepts, so some parts of the
+book end up having to refer you to portions that you haven't read yet. The
+chapters and sections are sorted so that <em>minimal</em> future references are
+required, but it's unavoidable.</p>
+<p>The actual &quot;tutorial order&quot; of the book is the
+<a href="../05-examples/00-index.html">Examples</a> chapter. Each section of that chapter
+breaks down one of the provided examples in the <a href="https://github.com/rust-console/gba/tree/master/examples">examples
+directory</a> of the
+repository. We go over what sections of the book you'll need to have read for
+the example code to make sense, and also how we apply the general concepts
+described in the book to the specific example cases.</p>
 <a class="header" href="#development-setup" id="development-setup"><h1>Development Setup</h1></a>
-<a class="header" href="#hello-magic" id="hello-magic"><h1>Hello Magic</h1></a>
+<p>Before you can build a GBA game you'll have to follow some special steps to
+setup the development environment.</p>
+<p>Once again, extra special thanks to <strong>Ketsuban</strong>, who first dove into how to
+make this all work with rust and then shared it with the world.</p>
+<a class="header" href="#per-system-setup" id="per-system-setup"><h2>Per System Setup</h2></a>
+<p>Obviously you need your computer to have a <a href="https://rustup.rs/">working rust
+installation</a>. However, you'll also need to ensure that
+you're using a nightly toolchain (we will need it for inline assembly, among
+other potential useful features). You can run <code>rustup default nightly</code> to set
+nightly as the system wide default toolchain, or you can use a <a href="https://github.com/rust-lang-nursery/rustup.rs#the-toolchain-file">toolchain
+file</a> to use
+nightly just on a specific project, but either way we'll be assuming the use of
+nightly from now on. You'll also need the <code>rust-src</code> component so that
+<code>cargo-xbuild</code> will be able to compile the core crate for us in a bit, so run
+<code>rustup component add rust-src</code>.</p>
+<p>Next, you need <a href="https://devkitpro.org/wiki/Getting_Started">devkitpro</a>. They've
+got a graphical installer for Windows that runs nicely, and I guess <code>pacman</code>
+support on Linux (I'm on Windows so I haven't tried the Linux install myself).
+We'll be using a few of their general binutils for the <code>arm-none-eabi</code> target,
+and we'll also be using some of their tools that are specific to GBA
+development, so <em>even if</em> you already have the right binutils for whatever
+reason, you'll still want devkitpro for the <code>gbafix</code> utility.</p>
+<ul>
+<li>On Windows you'll want something like <code>C:\devkitpro\devkitARM\bin</code> and
+<code>C:\devkitpro\tools\bin</code> to be <a href="https://stackoverflow.com/q/44272416/455232">added to your
+PATH</a>, depending on where you
+installed it to and such.</li>
+<li>On Linux you can use pacman to get it, and the default install puts the stuff
+in <code>/opt/devkitpro/devkitARM/bin</code> and <code>/opt/devkitpro/tools/bin</code>. If you need
+help you can look in our repository's
+<a href="https://github.com/rust-console/gba/blob/master/.travis.yml">.travis.yml</a>
+file to see exactly what our CI does.</li>
+</ul>
+<p>Finally, you'll need <code>cargo-xbuild</code>. Just run <code>cargo install cargo-xbuild</code> and
+cargo will figure it all out for you.</p>
+<a class="header" href="#per-project-setup" id="per-project-setup"><h2>Per Project Setup</h2></a>
+<p>Once the system wide tools are ready, you'll need some particular files each
+time you want to start a new project. You can find them in the root of the
+<a href="https://github.com/rust-console/gba">rust-console/gba repo</a>.</p>
+<ul>
+<li><code>thumbv4-none-agb.json</code> describes the overall GBA to cargo-xbuild (and LLVM)
+so it knows what to do. Technically the GBA is <code>thumbv4-none-eabi</code>, but we
+change the <code>eabi</code> to <code>agb</code> so that we can distinguish it from other <code>eabi</code>
+devices when using <code>cfg</code> flags.</li>
+<li><code>crt0.s</code> describes some ASM startup stuff. If you have more ASM to place here
+later on this is where you can put it. You also need to build it into a
+<code>crt0.o</code> file before it can actually be used, but we'll cover that below.</li>
+<li><code>linker.ld</code> tells the linker all the critical info about the layout
+expectations that the GBA has about our program, and that it should also
+include the <code>crt0.o</code> file with our compiled rust code.</li>
+</ul>
+<a class="header" href="#compiling" id="compiling"><h2>Compiling</h2></a>
+<p>Once all the tools are in place, there's particular steps that you need to
+compile the project. For these to work you'll need some source code to compile.
+Unlike with other things, an empty main file and/or an empty lib file will cause
+a total build failure, because we'll need a
+<a href="https://rust-embedded.github.io/book/intro/no-std.html">no_std</a> build, and rust
+defaults to builds that use the standard library. The next section has a minimal
+example file you can use (along with explanation), but we'll describe the build
+steps here.</p>
+<ul>
+<li>
+<p><code>arm-none-eabi-as crt0.s -o target/crt0.o</code></p>
+<ul>
+<li>This builds your text format <code>crt0.s</code> file into object format <code>crt0.o</code>
+that's placed in the <code>target/</code> directory. Note that if the <code>target/</code>
+directory doesn't exist yet it will fail, so you have to make the directory
+if it's not there. You don't need to rebuild <code>crt0.s</code> every single time,
+only when it changes, but you might as well throw a line to do it every time
+into your build script so that you never forget because it's a practically
+instant operation anyway.</li>
+</ul>
+</li>
+<li>
+<p><code>cargo xbuild --target thumbv4-none-agb.json</code></p>
+<ul>
+<li>This builds your Rust source. It accepts <em>most of</em> the normal options, such
+as <code>--release</code>, and options, such as <code>--bin foo</code> or <code>--examples</code>, that you'd
+expect <code>cargo</code> to accept.</li>
+<li>You <strong>can not</strong> build and run tests this way, because they require <code>std</code>,
+which the GBA doesn't have. If you want you can still run some of your
+project's tests with <code>cargo test --lib</code> or similar, but that builds for your
+local machine, so anything specific to the GBA (such as reading and writing
+registers) won't be testable that way. If you want to isolate and try out
+some piece code running on the GBA you'll unfortunately have to make a demo
+for it in your <code>examples/</code> directory and then run the demo in an emulator
+and see if it does what you expect.</li>
+<li>The file extension is important! It will work if you forget it, but <code>cargo xbuild</code> takes the inclusion of the extension as a flag to also compile
+dependencies with the same sysroot, so you can include other crates in your
+build. Well, creates that work in the GBA's limited environment, but you get
+the idea.</li>
+</ul>
+</li>
+</ul>
+<p>At this point you have an ELF binary that some emulators can execute directly
+(more on that later). However, if you want a &quot;real&quot; ROM that works in all
+emulators and that you could transfer to a flash cart to play on real hardware
+there's a little more to do.</p>
+<ul>
+<li>
+<p><code>arm-none-eabi-objcopy -O binary target/thumbv4-none-agb/MODE/BIN_NAME target/ROM_NAME.gba</code></p>
+<ul>
+<li>This will perform an <a href="https://linux.die.net/man/1/objcopy">objcopy</a> on our
+program. Here I've named the program <code>arm-none-eabi-objcopy</code>, which is what
+devkitpro calls their version of <code>objcopy</code> that's specific to the GBA in the
+Windows install. If the program isn't found under that name, have a look in
+your installation directory to see if it's under a slightly different name
+or something.</li>
+<li>As you can see from reading the man page, the <code>-O binary</code> option takes our
+lovely ELF file with symbols and all that and strips it down to basically a
+bare memory dump of the program.</li>
+<li>The next argument is the input file. You might not be familiar with how
+<code>cargo</code> arranges stuff in the <code>target/</code> directory, and between RLS and
+<code>cargo doc</code> and stuff it gets kinda crowded, so it goes like this:
+<ul>
+<li>Since our program was built for a non-local target, first we've got a
+directory named for that target, <code>thumbv4-none-agb/</code></li>
+<li>Next, the &quot;MODE&quot; is either <code>debug/</code> or <code>release/</code>, depending on if we had
+the <code>--release</code> flag included. You'll probably only be packing release
+mode programs all the way into GBA roms, but it works with either mode.</li>
+<li>Finally, the name of the program. If your program is something out of the
+project's <code>src/bin/</code> then it'll be that file's name, or whatever name you
+configured for the bin in the <code>Cargo.toml</code> file. If your program is
+something out of the project's <code>examples/</code> directory there will be a
+similar <code>examples/</code> sub-directory first, and then the example's name.</li>
+</ul>
+</li>
+<li>The final argument is the output of the <code>objcopy</code>, which I suggest putting
+at just the top level of the <code>target/</code> directory. Really it could go
+anywhere, but if you're using git then it's likely that your <code>.gitignore</code>
+file is already setup to exclude everything in <code>target/</code>, so this makes sure
+that your intermediate game builds don't get checked into your git.</li>
+</ul>
+</li>
+<li>
+<p><code>gbafix target/ROM_NAME.gba</code></p>
+<ul>
+<li>The <code>gbafix</code> tool also comes from devkitpro. The GBA is very picky about a
+ROM's format, and <code>gbafix</code> patches the ROM's header and such so that it'll
+work right. Unlike <code>objcopy</code>, this tool is custom built for GBA development,
+so it works just perfectly without any arguments beyond the file name. The
+ROM is patched in place, so we don't even need to specify a new destination.</li>
+</ul>
+</li>
+</ul>
+<p>And you're <em>finally</em> done!</p>
+<p>Of course, you probably want to make a script for all that, but it's up to you.
+On our own project we have it mostly set up within a <code>Makefile.toml</code> which runs
+using the <a href="https://github.com/sagiegurari/cargo-make">cargo-make</a> plugin.</p>
+<a class="header" href="#hello-magic" id="hello-magic"><h1>Hello, Magic</h1></a>
+<p>So we know all the steps to build our source, we just need some source.</p>
+<p>We're beginners, so we'll start small. With normal programming there's usually a
+console available, so the minimal program prints &quot;Hello, world&quot; to the terminal.
+On a GBA we don't have a terminal and standard out and all that, so the minimal
+program draws a red, blue, and green dot to the screen.</p>
+<p>At the lowest level of device programming, it's all <a href="https://en.wikipedia.org/wiki/Magic_number_(programming)">Magic
+Numbers</a>. You write
+special values to special places and then the hardware does something. A clear
+API makes every magic number and magic location easy to understand. A clear <em>and
+good</em> API also prevents you from using the wrong magic number in the wrong place
+and causing problems for yourself.</p>
+<p>This is the minimal example to just test that our build system is all set, so
+just this once we'll go <em>full</em> magic number crazy town, for fun. Ready? Here
+goes:</p>
+<p><code>hello_magic.rs</code>:</p>
+<pre><pre class="playpen"><code class="language-rust">#![feature(start)]
+#![no_std]
+
+#[panic_handler]
+fn panic(_info: &amp;core::panic::PanicInfo) -&gt; ! {
+  loop {}
+}
+
+#[start]
+fn main(_argc: isize, _argv: *const *const u8) -&gt; isize {
+  unsafe {
+    (0x400_0000 as *mut u16).write_volatile(0x0403);
+    (0x600_0000 as *mut u16).offset(120 + 80 * 240).write_volatile(0x001F);
+    (0x600_0000 as *mut u16).offset(136 + 80 * 240).write_volatile(0x03E0);
+    (0x600_0000 as *mut u16).offset(120 + 96 * 240).write_volatile(0x7C00);
+    loop {}
+  }
+}
+</code></pre></pre>
+<p>Throw that into your project skeleton, build the program, and give it a run. You
+should see a red, green, and blue dot close-ish to the middle of the screen. If
+you don't, something <em>already</em> went wrong. Double check things, phone a friend,
+write your senators, try asking <code>Lokathor</code> or <code>Ketsuban</code> on the <a href="https://discordapp.com/invite/aVESxV8">Rust Community
+Discord</a>, until you're eventually able to
+get your three dots going.</p>
+<p>Of course, I'm sure you want to know why those numbers are the numbers to use.
+Well that's what the whole rest of the book is about!</p>
+<a class="header" href="#newtype" id="newtype"><h1>Newtype</h1></a>
+<p>There's one thing I want to get out of the way near the start of the book and it
+didn't really have a good fit anywhere else in the book so it goes right here.</p>
+<p>We're talking about the &quot;Newtype Pattern&quot;!</p>
+<p>Now, I told you to read the Rust Book before you read this book, and I'm sure
+you're all good students who wouldn't sneak into this book without doing the
+required reading, so I'm sure you all remember exactly what I'm talking about,
+because they touch on the newtype concept in the book twice, in two <em>very</em> long
+named sections:</p>
+<ul>
+<li><a href="https://doc.rust-lang.org/book/ch19-03-advanced-traits.html#using-the-newtype-pattern-to-implement-external-traits-on-external-types">Using the Newtype Pattern to Implement External Traits on External
+Types</a></li>
+<li><a href="https://doc.rust-lang.org/book/ch19-04-advanced-types.html#using-the-newtype-pattern-for-type-safety-and-abstraction">Using the Newtype Pattern for Type Safety and
+Abstraction</a></li>
+</ul>
+<p>...Yeah... The Rust Book doesn't know how to make a short sub-section name to
+save its life. Shame.</p>
+<a class="header" href="#newtype-basics" id="newtype-basics"><h2>Newtype Basics</h2></a>
+<p>So, we have all these pieces of data, and we want to keep them separated, and we
+don't wanna pay the cost for it at runtime. Well, we're in luck, we can pay the
+cost at compile time.</p>
+<pre><pre class="playpen"><code class="language-rust">
+# #![allow(unused_variables)]
+#fn main() {
+pub struct PixelColor(u16);
+#}</code></pre></pre>
+<p>Ah, except that, as I'm sure you remember from <a href="https://doc.rust-lang.org/nomicon/other-reprs.html#reprtransparent">The
+Rustonomicon</a>
+(and from <a href="https://github.com/rust-lang/rfcs/blob/master/text/1758-repr-transparent.md">the
+RFC</a>
+too, of course), if we have a single field struct that's sometimes different
+from having just the bare value, so we should be using <code>#[repr(transparent)]</code>
+with our newtypes.</p>
+<pre><pre class="playpen"><code class="language-rust">
+# #![allow(unused_variables)]
+#fn main() {
+#[repr(transparent)]
+pub struct PixelColor(u16);
+#}</code></pre></pre>
+<p>Ah, and of course we'll need to make it so you can unwrap the value:</p>
+<pre><pre class="playpen"><code class="language-rust">
+# #![allow(unused_variables)]
+#fn main() {
+#[repr(transparent)]
+pub struct PixelColor(u16);
+
+impl From&lt;PixelColor&gt; for u16 {
+  fn from(color: PixelColor) -&gt; u16 {
+    color.0
+  }
+}
+#}</code></pre></pre>
+<p>And then we'll need to do that same thing for <em>every other newtype we want</em>.</p>
+<p>Except there's only two tiny parts that actually differ between newtype
+declarations: the new name and the base type. All the rest is just the same rote
+code over and over. Generating piles and piles of boilerplate code? Sounds like
+a job for a macro to me!</p>
+<a class="header" href="#making-it-a-macro" id="making-it-a-macro"><h2>Making It A Macro</h2></a>
+<p>The most basic version of the macro we want goes like this:</p>
+<pre><pre class="playpen"><code class="language-rust">
+# #![allow(unused_variables)]
+#fn main() {
+#[macro_export]
+macro_rules! newtype {
+  ($new_name:ident, $old_name:ident) =&gt; {
+    #[repr(transparent)]
+    pub struct $new_name($old_name);
+  };
+}
+#}</code></pre></pre>
+<p>Except we also want to be able to add attributes (which includes doc comments),
+so we upgrade our macro a bit:</p>
+<pre><pre class="playpen"><code class="language-rust">
+# #![allow(unused_variables)]
+#fn main() {
+#[macro_export]
+macro_rules! newtype {
+  ($(#[$attr:meta])* $new_name:ident, $old_name:ident) =&gt; {
+    $(#[$attr])*
+    #[repr(transparent)]
+    pub struct $new_name($old_name);
+  };
+}
+#}</code></pre></pre>
+<p>And we want to automatically add the ability to turn the wrapper type back into
+the wrapped type.</p>
+<pre><pre class="playpen"><code class="language-rust">
+# #![allow(unused_variables)]
+#fn main() {
+#[macro_export]
+macro_rules! newtype {
+  ($(#[$attr:meta])* $new_name:ident, $old_name:ident) =&gt; {
+    $(#[$attr])*
+    #[repr(transparent)]
+    pub struct $new_name($old_name);
+    
+    impl From&lt;$new_name&gt; for $old_name {
+      fn from(x: $new_name) -&gt; $old_name {
+        x.0
+      }
+    }
+  };
+}
+#}</code></pre></pre>
+<p>That seems like enough for all of our examples, so we'll stop there. We could
+add more things, such as making the <code>From</code> impl optional (because what if you
+shouldn't unwrap it for some weird reason?), allowing for more precise
+visibility controls (on both the newtype overall and the inner field), and maybe
+even other things I can't think of right now. We won't really need those in our
+example code for this book, so it's probably nicer to just keep the macro
+simpler and quit while we're ahead.</p>
+<p><strong>As a reminder:</strong> remember that macros have to appear <em>before</em> they're invoked in
+your source, so the <code>newtype</code> macro will always have to be at the very top of
+your file, or in a module that's declared before other modules and code.</p>

+<p>So you're stuck on a problem and the book doesn't say what to do. Where can you
+find out more?</p>
+<p>The first place I would suggest is the <a href="https://discordapp.com/invite/aVESxV8">Rust Community
+Discord</a>. If it's a general Rust question
+then you can ask anyone in any channel you feel is appropriate. If it's GBA
+specific then you can try asking me (<code>Lokathor</code>) or <code>Ketsuban</code> in the <code>#gamedev</code>
+channel.</p>
+<a class="header" href="#emulators" id="emulators"><h2>Emulators</h2></a>
+<p>You certainly might want to eventually write a game that you can put on a flash
+cart and play on real hardware, but for most of your development you'll probably
+want to be using an emulator for testing, because you don't have to fiddle with
+cables and all that.</p>
+<p>In terms of emulators, you want to be using
+<a href="https://github.com/mgba-emu/mgba">mGBA</a>, and you want to be using the <a href="https://github.com/mgba-emu/mgba/releases/tag/0.7-b1">0.7 Beta
+1</a> or later. This update
+lets you run raw ELF files, which means that you can have full debug symbols
+available while you're debugging problems.</p>
+<a class="header" href="#information-resources" id="information-resources"><h2>Information Resources</h2></a>
+<p>Ketsuban and I didn't magically learn this all from nowhere, we read various
+technical manuals and guides ourselves and then distilled the knowledge (usually
+oriented towards C and C++) into this book for Rust.</p>
+<p>We have personally used some or all of the following:</p>
+<ul>
+<li><a href="http://problemkaputt.de/gbatek.htm">GBATEK</a>: This is <em>the</em> resource. It
+covers not only the GBA, but also the DS and DSi, and also a run down of ARM
+assembly (32-bit and 16-bit opcodes). The link there is to the 2.9b version on
+<code>problemkaputt.de</code> (the official home of the document), but if you just google
+for gbatek the top result is for the 2.5 version on <code>akkit.org</code>, so make sure
+you're looking at the newest version. Sometimes <code>problemkaputt.de</code> is a little
+sluggish so I've also <a href="https://lokathor.com/gbatek.html">mirrored</a> the 2.9b
+version on my own site as well. GBATEK is rather large, over 2mb of text, so
+if you're on a phone or similar you might want to save an offline copy to go
+easy on your data usage.</li>
+<li><a href="https://www.coranac.com/tonc/text/">TONC</a>: While GBATEK is basically just a
+huge tech specification, TONC is an actual <em>guide</em> on how to make sense of the
+GBA's abilities and organize it into a game. It's written for C of course, but
+it's a large</li>
+<li><a href="https://www.cs.rit.edu/%7Etjh8300/CowBite/CowBiteSpec.htm">CowBite</a>: This is
+more like GBATEK, and it's less complete, but it mixes in a little more
+friendly explanation of things in between the hardware spec parts.</li>
+</ul>
+<p>And I haven't had time to look at it myself, <a href="http://belogic.com/gba/">The Audio
+Advance</a> seems to be very good. It explains in depth
+how you can get audio working on the GBA. Note that the table of contents for
+each page goes along the top instead of down the side.</p>
+<a class="header" href="#non-rust-gba-community" id="non-rust-gba-community"><h2>Non-Rust GBA Community</h2></a>
+<p>There's also the <a href="http://www.gbadev.org/">GBADev.org</a> site, which has a forum
+and everything. They're coding in C and C++, but you can probably overcome that
+difference with a little work on your part.</p>
+<p>I also found a place called
+<a href="https://gbatemp.net/categories/nintendo-gba-discussions.32/">GBATemp</a>, which
+seems to have a more active forum but less of a focus on actual coding.</p>
