An extremely rare cartridge that was used to test Game Boy Advance systems. By default, the system will boot straight into the aging test, but the menu can be accessed by holding L + R at startup. From within the menu, you can run various tests and also modify the default startup behavior of the cartridge.

Of course, being used to test official GBA hardware also makes it useful for testing unofficial GBA emulators and hardware clones. The results are quite interesting:

• Most emulators don't pass every test (at least at the current moment), and in some cases will crash partway through the tests.
• Similarly, some hardware clones will either fail one or more of the tests or crash before the testing is finished.
• Currently, the only ones that fully pass the tests are the NanoBoyAdvance emulator, the MiSTerFPGA GBA core, and the emulator included with Game Boy Advance - Nintendo Switch Online, although that doesn't necessarily mean those are the most generally-accurate emulators.

Five versions of the test program have been found: v1.0, v7.0, v7.1, v9.0, and v10.0, the last of which was leaked online through Nintendo's official GBA emulator for the Nintendo Switch. This page currently covers v7.0.

Unused Graphics

A crossed-out hand that can only be seen for a split-second when switching from the Donkey Kong Advance screen.

Small pixelated frames of Mario's head based on the Super Mario 64 opening screen. Only two of these frames are used.

This "Donkey Kong Advance" logo is used, but the "Advance" portion is almost entirely obscured by other graphics:
