# 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.

## Requirements & limits

- **Prerequisites:** Provide your own Flicky (UE) cartridge ROM.
- **Prerequisites:** Python 3, GNU Make, and Retrolarium Kit are required for the documented build.
- **Testing evidence:** Full runtime checks use MAME and the studio check needs the Flicky level writer.
- **License:** No licence file in the repository.
