  "description_en": "Toy Story disassembly reconstructs the Mega Drive game's ROM as generated assembly source and compares the rebuilt ROM byte for byte with the user's copy. Its 68000 tracer, ROM maps, RNC decoder, and sprite tools support ongoing recovery of routines, text, and graphics formats. The author reports that the rebuild matches while equivalent named source remains incomplete.",
