Checksum Test

Passed	Failed

Hold Up + 1 + 2 when powering on the system and after the Sega logo the game will perform a ROM checksum test. Once it's complete, the ROM checksum along with the game's build date (in DDMMYY format) and time will be shown. If the checksum test passes, a smiley face on a green background will be displayed. If the checksum test fails, the game will display a dead face on a red background and play a constant buzzing tone.
