  "description_en": "Alien Trilogy reconstructs C source for the USA PlayStation game executable SLUS_000.07 using its original GCC 2.5.7 toolchain. Per-function comparisons check rebuilt code and relocations against retail bytes; a gate overlays rebuilt units on the user's executable and checks the complete hash. The author reports 645 byte-matched game C functions, with remaining gaps and pending source-quality work documented.",
