# Crash Twinsanity: a C++ reconstruction of the PAL PS2 executable

> Crash Twinsanity reconstructs the PAL PlayStation 2 game’s executable in C++, using a platform layer and data split from the user’s original executable. The author reports that the build boots and plays in PCSX2 with matching boot state, frame output and saves. The build tools also generate assembly from the user’s executable for a byte-matching comparison.
