tevlon posts a browser-playable NES Contra port built by translating vermiceli's annotated 6502 disassembly into C, checked frame-by-frame against the original in the Mesen emulator, then compiled to WebAssembly with added online co-op multiplayer.

“I ported it in two steps. First to C: the game logic is translated routine by routine from the 6502 assembly, and checked frame by frame against the original in the Mesen emulator.”
