SNES Test Cartridge

I assume this cartridge acts like another popular test cart for the NES, in that it tests the various hardware components of the SNES for errors, and alerts the technicians of any errors. What it specifically tests, is not currently known. This was designed to test the SNES console for a specific period of time, or "burn-in", to make sure everything worked.
