A reverse-engineering project recompiles The Binding of Isaac: Repentance for browser play using WebAssembly.

Landing page captured for the 2026-10-09 issue.

For: Browser players and game reverse engineers
Worth noticing: The page says the port uses original game code, not an emulator or interpreter, and currently requires Chrome, WebAssembly JSPI, and WebGL2.

Field notes

The project page lays out a pipeline from a Windows executable through Ghidra-generated C and Emscripten to WebAssembly, with a thin host layer replacing several Windows-facing components. It says the result uses the original game code, including its bugs, and notes requirements for WebAssembly JSPI and WebGL2. The same page lists a separate Telegram gift-backdrop matcher covering 64 collections, with JSON and CSV output.
