CHIP-8 Interpreter

This is my CHIP-8 interpreter. It is written in Rust using the minifb crate.

Usage

./chip-8 <rom> [background color] [foreground color]

Keyboard Input

The first three rows of keys are accessible using:

E R T Y
D F G H
C V B N

The last row is accessible using Space + C/V/B/N.

Toggle Quirky Behavior

When I started writing this interpreter, I wanted it to be fully compatible with the original interpreter in the COSMAC VIP manual. However, I noticed that most, if not all modern CHIP-8 roms rely on different 'quirky' behavior for shifting instructions (8XY6 and 8XYE) and register saving/restoring instructions (FX55 and FX65). That's why quirky behavior is enabled by default but you can disable it in the Cargo.toml file.
