GameCube Service Disc v1.0/03

GameCube Service Disc v1.0/03 was once used by Nintendo World Class Service to test and diagnose problems with the console, memory cards, controllers, and can even check the currently inserted Game Boy Advance game through the GameCube-Game Boy Advance Cable. Nintendo 64 controllers can also be detected, suggesting this is from earlier in the console's development.

As with all Nintendo testing software, the Service Disc contains a plethora of Nintendo-themed content, both used and unused. Bizarrely, there are also respectable logos from the automotive industry, such as Tamiya and Goodyear.
