This needs some investigation.
Discuss ideas and findings on the talk page.
Specifically:

Investigate the [https://hiddenpalace.org/Micro_Machines_(Oct_22,_1993_prototype) October 1993 prototype] on Hidden Palace.
A later revision of the game from August 1994 exists and has a different checksum - check for differences between versions.

Checksum Test#

Game Gear	Master System

Hold Up + 1 + 2 when powering on the system and 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.
