Case study

ToeJam & Earl: matching Sega Genesis decompilation

ToeJam & Earl reconstructs two Sega Genesis retail revisions as matched C and readable 68000 and Z80 assembly. Build tools extract typed assets from the user's ROM and compare each rebuilt image with the original; the author reports byte-identical builds for both revisions.
