Case study

ToeJam & Earl: an incomplete REV 02 Genesis disassembly

tje-disasm investigates the REV 02 Sega Genesis release of ToeJam & Earl through assembly source, ROM tools and documented code comparisons with REV 00. Its notes examine function-level differences and possible compiler fingerprints. The project requires a user-supplied REV 02 ROM and describes the disassembly as incomplete.
