The game - Diagnostic Test Cartridge - Atari 7800 | A7800

After starting, the cartridge tests the entire system for 10 seconds. If everything is fine, a screen appears on which you can set up your TV or monitor.

A numerical code also appears, and in the worst case, even a disgruntled smiley.

It is very unclear why, in the cartridge there is a piece of code from Atari 2600.
