An implementation of the CHIP-8 programming language in Rust.
The sound library requires you to install a package on Linux to build successfully:
sudo apt-get install libsdl2-dev
Given a CHIP-8 ROM, you can start the ROM in the emulator like so:
cargo run romfile.ch8
Here is a large set of ROMs I found.
The emulator runs at 480 Hz and updates the delay and sound timers (and the screen) once every 8 cycles, so at 60 Hz. The input is mapped similarly to most other CHIP-8 emulators I have come across:
| Row 1 | Row 2 | Row 3 | Row 4 |
|---|---|---|---|
| 1 - 1 | 2 - 2 | 3 - 3 | C - 4 |
| 4 - Q | 5 - W | 6 - E | D - R |
| 7 - A | 8 - S | 9 - D | F - 4 |
| A - Z | 0 - X | B - C | F - V |
The screen runs at the default resolution of 64x32, scaled up 8x for better visibility.
