README
chip8-rs
========
CHIP-8 implementation in Rust, compiled to wasm. [Live Demo](https://faizilham.github.io/lab/chip8/)
Features
--------
- All CHIP-8 standard features
- Includes 90 ROMs from CHIP-8 pack
- Emulates afterglow in old phosphor screen to reduce flickering (can be turned off)
- Handles 3 implementation quirks that can be enabled:
1. Shift quirk: opcodes 8xy6 & 8xyE shift Vy instead of Vx
2. Load/Store register quirk: opcodes Fx55 & Fx65 won't increase I register by x + 1
3. Sprite wrapping quirk: when parts of sprite are drawn outside of display, wrap it instead of clipping it
- Lightweight page (transfer size < 30kb, total size < 70kb)
