Based on vermiceli's annotated disassembly of Contra: https://github.com/vermiceli/nes-contra-us . Thanks for the great work. 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. Then the C code to WebAssembly so it runs in the browser. The cherry on top: online multiplayer, so two players can play co-op over the internet. Source: https:/&#
