A Minimal Chip8 Emulator Written in Rust

See the Online demo of the emulator.

Overview

Project features:

• Emulates the CHIP8 only (not the Super/Mega variants)
• #[no_std] and lightweight implementation of the emulator is provided in the Rust crate packages/chip8. The crate is designed to be easily cross-compiled on very constrained platforms.
• WebAssembly version of the emulator in app/chip8-wasm, for running chip8 in a Web browser. The WASM version of the chip8 interpreter fits in less than 4K bytes!
• Simple OpenGL + SDL2 GUI for running the emulator in app/chip8-emu

TODOs

A random list of possible future improvements of the project:

• Build instruction
• API clean-up and documentation
• Support CHIP8 variants
• (Not sure) C bindings + Qt Gui (as a replacement for chip8-emu)?
• WASM:
  • Configurable keybindings
  • Show CPU state
  • A bit of retro styling?
