CHIP-8 Emulator in Rust

A simple CHIP-8 emulator written in Rust using SDL2 for graphics and input.

Features

• Full CPU emulation for all CHIP-8 opcodes
• SDL2-based rendering (64x32 resolution)
• Keyboard input handling
• Timer support (delay and sound)
• ROM loading from a directory
• Accurate fetch-decode-execute cycle

ROM Directory

CHIP-8 ROMs (.ch8 files) should be placed inside the binary_assets/ directory.

Example:

│   ├── Blitz.ch8
│   ├── Invaders.ch8
│   ├── Pong.ch8
│   ├── Rocket.ch8
│   ├── Tank.ch8
│   └── Tetris.ch8
