GoKawiilDeveloper ports NES Contra (1987) to WebAssembly for browser play
A developer has converted the original 1987 NES game Contra by translating its assembly code into C and then compiling it to WebAssembly, allowing it to run natively in a web browser. The Show HN project includes single-player and online two-player modes, with the latter supporting invite links so a remote friend can join a session.
GoKawiil's interpretation of the reporting above, not reported fact.
The project demonstrates how old console binaries can be systematically decompiled and recompiled for modern web runtimes, a technique that could help preserve classic games without emulator dependencies. It also shows WebAssembly's growing suitability for real-time, input-sensitive applications like multiplayer retro gaming directly in the browser.
- Contra (1987) was ported from NES assembly to C, then compiled to WebAssembly
