dot-matrix-rs

This is a complete rewrite of my Game Boy emulator, Dot Matrix, into Rust. This emulator was built to help me learn rust as well as get a better understanding of the Game Boy hardware.

Implementation Differences from dot-matrix (C++)

• Timing (both the clock and timers) is properly emulated
• PPU background rendering is more accurate and window/object rendering has been added
• Joypad inputs
• Memory banking
• Savestates (F1/F2)

Out of Scope:

• Pixel FIFO
• APU
