Case study

Project Pyrrhus: a static recompilation of Killzone 2 for PC

Project Pyrrhus builds a native Windows x64 port of the PS3 game Killzone 2 by statically recompiling code from a user's disc, matching version 1.29 update, and decrypted EBOOT. Its tooling lifts PPU code with a patched ps3recomp and builds a Direct3D 12 executable. The author reports that the prerelease reaches menus and plays the first level.
