# .hack//INFECTION: an early matching PlayStation 2 decompilation

> .hack//INFECTION reconstructs source for the North American PlayStation 2 release and uses objdiff to compare compiled functions with objects generated from the user’s retail executable. Its initial progress scope covers resident Emotion Engine functions, with one function reported as matching after call-relocation normalization. Overlays, VU microcode and IOP modules remain outside that scope.
