m68k-nibbles

Nibbles for the Motorola 68000, with the original nibbles.asm source plus a modern terminal-first interpreter and CI/test reporting setup.

Current Status

nibbles.asm is still the source of truth for the game.
The repo now includes a vendored React/Yarn workspace version of m68k-interpreter in references/m68k-interpreter.
That interpreter has been extended with the Easy68K subset needed by Nibbles:
- compatibility loader for the Nibbles assembly dialect
- runtime support for the instructions and addressing modes used by the game
- terminal device support for the game’s text-screen output
- keyboard input and trap handling for gameplay
- IDE support for loading and running Nibbles directly
The interpreter is split into separate workspace packages:
- packages/interpreter
- packages/ide
Test coverage and CI results are now reported through test-station for both:
- the Nibbles-focused project surface
- the full interpreter workspace

The current recommended way to play is through the vendored interpreter workspace.

coming soon

Then open the local Vite URL, click Load Nibbles, and press Run.
