RustBoyAdvance-NG

Build Status

RustBoyAdvance-NG aims to be a Nintendo GameBoy Advance emulator and debugger, written in the rust programming language.

RustBoyAdvance-NG currently has implemented

  • Dumbed-down ARM/THUMB mode disassembling
  • Some ARM/THUMB instruction are implemented, but not all of them.
  • A neat debugger REPL

But the way for full emulation is way far ahead, because most of the ARM/THUMB instructions are not yet implemented.

Using the REPL

You need to have rust installed, and somehow legally obtain a gba bios binary. Currently to test the debugger, any binary file containing arm mode instructions will do.

$ cargo run -- debug

Why is this project needed ?

It's actually not. There are quite a lot of GBA emulators, and even some written in rust. Actually, I couldn't find any game capable emulators written in rust.

I'm only doing this as a side project intended for learning rust.

This is my third take on this project. My first go at this was about 3 years ago, but I didn't like rust much at the time so it got abandoned. I tried to resurrect it a year ago but didn't have the time to get invested in a side-project, let alone learning rust.

I've grown to like rust a lot since then, so here we go again. You know what they say, third time's a charm.
