Case study

Flicky: byte-identical Mega Drive source reconstruction

Flicky reconstructs the Sega Mega Drive game's 68000 code and Z80 sound driver as annotated assembly. Build scripts split data from the user's ROM, assemble the source, and compare the resulting cartridge image byte for byte; recorded input movies support runtime checks in MAME.
