A chip-8 virtual machine written in OCaml.

• All opcodes and flag behaviour verified against Chip8 specific test roms.
• Most quirks (other than clipping, which is WIP)
• Configurable colours & render scale
• A rudementary debugger
• Audio

• SDL2
• OCaml 5

$ opam install . --deps-only --with-test
# run tests
$ dune build
$ dune test
# build release and install in env
$ dune build --release
$ dune install

I found a bunch at the Chip8 Archive.

• Originally inspired by caml8, then I did my own thing.
• This excellent guide
• Another more practical guide
