# AC4-Port: native Windows port of Armored Core 4

> AC4-Port is an unofficial native Windows build of ARMORED CORE 4 for the PS3 USA release BLUS30027. The README describes static recompilation of about 3.6 million PowerPC instructions into C++, with SPU programs translated ahead of time, RSX commands drawn through Direct3D 11, and shaders converted to HLSL. The repository leaves out game data, game code, and keys.
