Game Boy Emulator

DMG-01 Emulator in Rust

This exists as a way to learn how to write an emulator and get some practice with Rust.

I intentionally endeavour to use the simplest Rust features possible.

Usage

  1. Get a ROM. Don't ask me where to find them.

  2. cargo run myrom.gb --noboot

Controls

Keyboard arrows, A, S, Z, X.

Boot Loader

There is a fully functional boot loader if you have dmg_rom.bin located in the data directory. If not, then you must use --noboot to skip running the bootloader and explicitly set all memory, flags, registers to the state that the boot loader would have set them to. Many games depend on assuming this state at initialization.
