A GameBoy (and hopefully in future, GameBoy Colour) emulator written in Rust.
This is very much a work in progress and can only render non-Gameboy Colour games. It can only render Tetris up to the main menu and slightly beyond before crashing. If you're looking for a proper working emulator, you've come to the wrong place :)
Here is the latest progress GIF. We can play Tetris!
The entire instruction set is now supported! As such, we can now play Tetris without it crashing at all. The progress GIF below shows a 2 game session of Tetris.
First and foremost this is a learning project for myself.
Ideally, this emulator will be able to run Tetris in both the DMG and GBC versions. After that, I will move on to other games.
If you want decent performance, you should compile and run this emulator with the --release flag:
cargo run --release -- --rom /path/to/rom.gb
If you want to contribute, please open an issue and discuss your planned contribution. I don't actually have a solid roadmap other than "support DMG Tetris" at the moment, so discussion around features is a good idea.
