Today we have released the NUS Controller Checker for the Nintendo 64! This is a prototype for the controller checker in the well known N64 Test Cartridge used by the Nintendo World Class Service Center to test and repair systems. This is quite notable as the N64 Test Cartridge has not yet successfully been able to be dumped, so this is the first time that we can get to play around with a piece of it! The label on the back reads “コントローラ検査器 NUS用Nカセット” (Controller Tester N Cassette for NUS).

While the back of the label indicates this as being Ver. 00, the actual ROM is labelled Ver. 1.01.
