RustBoyAdvance-NG is a free Nintendo Game Boy Advance emulator and debugger written in Rust. Its WebAssembly demo accepts ROM files by drag and drop, while the desktop emulator can open ROM files or ZIP archives containing .gba files when dropped into its window. Desktop use requires a GBA BIOS binary; the project says an open-source BIOS is supported. The repository lists SDL2 and minifb desktop frontends, though minifb is not maintained, and also includes Java JNI bindings, a terminal frontend, and a proof-of-concept Android app. The Android app can be opened in Android Studio and requires Rust Android targets with the NDK. A custom debugger and experimental GDB server are available behind build features. Desktop key bindings include saving snapshots with F5 and loading them with F9, but the bindings cannot currently be changed. Building the desktop app requires Rust 1.51 or later and SDL2 dependencies on Linux and macOS. The project lists CGB audio with four wave-generator channels among unfinished emulation work.
