  "description_en": "Psychonauts decompiles the PC game's modified Lua 4.0 scripts and portions of its 32-bit x86 engine into source checked by per-function byte comparisons. Its tools extract scripts from a user-owned game copy, rebuild them with a patched Lua compiler, and compare engine objects with Psychonauts.exe. The author reports all script functions matching and the engine still early in progress.",
