GeeBee

A barebones gameboy emulator written in Rust.

This emulator is in no shape or form attempting to be correct - merely good enough. This is a learning project for the fun of it.

How to

To build and run, use cargo:

$ cargo run -- -r path/to/rom.gbc

Controls

• WASD for directional pad
• N & M for B & A respectively
• Z for Start and X for Select.

What is done

• This emulator will successfully load bootroms for both DMG and CGB, and even somewhat play games.
• Tested under Windows and Linux.
• CPU instructions and instruction timings tests from Blargg's hardware test ROMs pass.
• There are still some rendering bugs associated with CGB mode.
• Some memory mapping issues still need to be ironed out.
