For whatever reason, the game list for the menu is included no less than four times inside the ROM. The copies of the list start at locations 0x608FA, 0x708FA, 0x10608FA and 0x10708FA.

Main Device Test

Hidden in the ROM is a program used to test the unit, which can be accessed by holding A + B and resetting it. The same test program can be found in the DreamGEAR MyArcade Retroplay Controller.
