An implementation of the CHIP-8 for Rust in ~350 lines of code.
CHIP-8 is a virtual machine (along with a supporting programming language). Since the CHIP-8 VM does not expose the fact that it's running on a host CPU, in theory the VM could be translated to physical hardware.
The CHIP-8 VM was used in the late '70s on some computers such as the Telmac 1800 and on some calculators in the 1980's.
CHIP-8 was mainly used as a gaming platform, and today you can play lots of games like Pong and Breakout on it.
Given a CHIP-8 ROM, you can start the ROM in the emulator like so:
cargo run romfile.ch8Here.
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.
