Bypassing Failed Input Port Test

As seen in this footage of Nintendo's factory, the cartridge expects the NES to be connected to a controller test jig. As no emulators currently have support for this test jig, the cartridge will fail when attempting to test the Zapper lines in the controller port.

Game Genie code TUEGIL will bypass this test and move on to the other tests in the cartridge.

Unused Graphics

The background scrolling test uses graphics copied from the NES port of Popeye, including some sprites that don't get shown during the test.
