CHIP-8 Emulator

A CHIP-8 emulator implemented in Rust with both native SDL2 and WebAssembly frontends.
Created following An Introduction to Chip-8 Emulation using the Rust Programming Language

Features

• Complete CHIP-8 instruction set implementation
• Cross-platform support (Native and Web)
• Configurable display colors (Native only)
• Real-time keyboard input
• Adjustable emulation speed
• Support for all standard CHIP-8 ROMs

Prerequisites

• Rust toolchain (cargo, rustc)
• SDL2 development libraries: Download from here
  On MacOS extract and place the extracted folder in /Library/Frameworks/
• wasm-pack
• python3 (to run a server for the web version)

Running

Native

Run in desktop folder: cargo run <path_to_rom> <color>
Color options: red, blue, green, pink

Web

Run in wasm folder:
wasm-pack build --target web && mv pkg/wasm.js ../web/wasm.js && mv pkg/wasm_bg.wasm ../web/wasm_bg.wasm && cd ../web && python3 -m http.server

Technical Details

• Written in Rust for performance and safety
• Uses SDL2 for native graphics and input handling
• WebAssembly support for browser-based emulation
