Matching decompilation of Alien Trilogy (PS1, SLUS_000.07)

A matching decompilation of Alien Trilogy for the PlayStation (USA, SLUS_000.07), built with the original PsyQ compiler and flags. Per its byte gate, about 49% of the executable now compiles from reconstructed C (645 functions); the GTE renderer stays as annotated assembly and the Sony libraries are identified. There is no playable port yet. The README says it was made with heavy AI help.
