//! This crate helps you write GBA ROMs.
//!
//! # SAFETY POLICY
//!
//! Some parts of this crate are safe wrappers around unsafe operations. This is
//! good, and what you'd expect from a Rust crate.
//!
//! However, the safe wrappers all assume that you will _only_ attempt to
//! execute this crate on a GBA or in a GBA Emulator.
//!
//! **Do not** use this crate in programs that aren't running on the GBA. If you
//! do, it's a giant bag of Undefined Behavior.
