PRESERVE THE SOURCE

The cartridge,
kept intact.

The supplied archive and its cartridge bytes are retained unchanged. This playable edition runs the original game through a self-hosted Genesis emulator. A required runtime header correction restores the original serial EEPROM save path for this [h1] dump. Optional cheats change runtime behavior.

The source is labeled UE [h1]. Coverage records distinguish decoded assets, runtime captures, measured audio loops and work still awaiting verification.

External save files and browser quick checkpoints contain paired emulator state and cartridge EEPROM data. The walkthrough checklist has its own export.
