Here's a book that'll help you program in Rust on the GBA.

It's very "work in progress". At the moment there's only one demo program.

If you want to contact us you should join the Rust Community Discord 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 also ask any of the few hundred other folks in the server as well.

If you want to read more about developing on the GBA there are some other good resources as well:

• Tonc, a tutorial series written for C, but it's what I based the ordering of this book's sections on.
• GBATEK, a homebrew tech manual for GBA/NDS/DSi. We will regularly link to parts of it when talking about various bits of the GBA.
• CowBite is another tech specification that's more GBA specific. It's sometimes got more ASCII art diagrams and example C struct layouts than GBATEK does.
