CHIP-8 is an interpreted bytecode, originally for the COSMAC VIP. It's also a fan favorite for learning to write VMs and interpreters. This is yet another CHIP-8 interpreter, written in Rust.
I had a week off work between Christmas and New Year and wanted to see how far I could get. I also wanted to do some more substantive Rust programming, instead of just doing some puzzles.
git clonecargo run -- -r <chip8rom.ch8>
Run with -h for help.
- Extendability. There are a number of variants of CHIP-8, and while I don't have implementations for each variant, the system is designed in such a way that e.g. implementing a larger screen should be trivial.
- Modularity. I have chosen to use
egui(viaeframe) for this initial implentation. However, any other graphics framework could be used in its place, by writing a harness that can poll myGraphicsAdapter. - Code Quality. I wanted to write something with a strong design, implemented well.
- Testing. Enough said.
- The [CHIP-8 Test ROM] (https://github.com/corax89/chip8-test-rom) and IBM test ROM both pass
- Many demo ROMs work well
- Initial support for keyboard I/O, with a few kinks to work out.
- Better output formatting, instead of Unicode filled-boxes in a monospaced font
- Fix I/O. Currently causes stuttering on some games
- More testing.
- Finish testing each instruction
- Add testing for decoding
- Add docs.
