Makes me think of all the code lost to poor storage. Like all my C64 related code from the 80s and 90s. I had hundreds of programs typed in regular notebooks.
The code for this game is really readable and easy to pick up after all these years of not doing any 6502 coding. Any 6502 wasm targets?
There's quite a few 8-bit CPU emulators that can be compiled to WASM. Static translation of 6502 (or Z80) machine code to WASM is tricky because a lot of 8-bit code was using self-modifying code, so you'd need at least some sort of JIT.
Shameless plug: I've started writing easy to integrate 8-bit chip emulators in standalone C headers a little while ago:

For instance used in these WASM emulators:
