# reo: recompiling Resident Evil Outbreak for Windows

> reo recompiles Resident Evil Outbreak for the PlayStation 2, NTSC-U SLUS-20765, to native Windows x86-64 with PS2Recomp. The README says a scripted boot reaches the first scenario in J's Bar, drawn by the game's own code, at about 35 times slower than real time. Sound output is not implemented, and play past that point has not been tried.
