Chris Covell released an bugfix for his Game Gear “HiColor” demo.

His notes:

Hi, folks. I’ve discovered (to my embarrassment) that this demo will not work properly on older GGs (without the BIOS) because I forgot to clear an important variable on startup. (The BIOS clears RAM beforehand, I’ll bet.) So, I’ve updated my demo and it should work fine on all Game Gear models.

Feel free to leave feedback on the linked webboard, no registration is required for that.
