NES Contra: a 6502 assembly port to C, then to WebAssembly
manni2000@manni2000
Someone took vermiceli's annotated Contra disassembly and translated the 6502 assembly routine by routine into C, checking each step frame by frame against the original in the Mesen emulator. Then the C went to WebAssembly so it runs in a browser tab. The cherry on top: online co-op, two players over the internet. Frame-by-frame checking is the kind of stubbornness this deserves.
