github.com 7 min read Editor score 7/10

The project translates PSP machine code ahead of time to C++, compiles it to WebAssembly, and links a small PSP OS and graphics reimplementation; the listed games run at up to 60 fps. The recompilation pipeline is technically substantial, though its application is game-focused.

What
PSP Web Recomp runs PSP games in browsers by recompiling their code to WebAssembly, without an emulator.
How
It translates MIPS machine code to C++, links a PSP operating-system and graphics reimplementation, and draws with WebGL2.
Why it matters
Its worker-thread graphics path and streamed game data show how legacy software can run in browsers with host-specific components.
