A Rust CHIP-8 VM implementation that doesn't use std. Other packages build on this
to implement a complete CHIP-8 computer on various platforms:
-
CHIRP-8 SDL (https://github.com/gergoerdi/chirp8-sdl) is an SDL-based implementation targeting "normal" computers. Its main use is in testing the engine itself.
-
CHIRP-8 AVR (https://github.com/gergoerdi/chirp8-avr) targets 8-bit AVR microcontrollers, and is intended to use with a simple circuit consisting of a small handful of components that are all breadboard-friendly.
