# Need for Speed: Porsche Unleashed: differential x86 source recovery

> prsche-disasm recovers C/C++ source for Need for Speed: Porsche Unleashed from its Windows x86 binaries. It indexes original modules and addresses, studies resource formats, and compares recovered functions with recorded original inputs, state, outputs, and ABI behavior. The recovered C++ modules build separately, but the full game does not yet link into a playable executable.
