I have Color Robot Battle cartridge for the TRS-80 Color Computer. It's a game where two people compete by writing programs for their robots (on screen) to play out trying to destroy each other.
What's odd though is that a few years ago I did find someone with a disk image of the game, though I'm quite certain it was never released on disk. The image seems to play fine but there is corruption on the menu screen.
I am not technically illiterate, but I do not have a ROM reader.
Here's some information about the game.
