The My Arcade Gamer V is an interesting device: It reuses the body of one of dreamGEAR's earlier handhelds while redoing the internals.
Unused Graphics#
Two tiles of the mountain on the title screen are missing. Making the tiles be used would make the title screen look like this:
Unused Audio#
Stored in the PCM data between the menu music and the cursor selection noise is... a clip of Ylvis' The Fox (What Does The Fox Say?). It is likely a remnant of software done by the same developers; the PVP Station Light 3000 uses 0:23 to 0:26 on the main menu. It is however totally unused here.
Unused Source Code#
At 0x7BE2E3 there is a big snippet of unused source code that might go to a game either in the console or to another one of the DreamGear consoles.
