    Since now i'm using my old non-backlit GBA only as a GBPlayer gamepad, i am thinking about making a batteryless mod.
    My idea is to bridge the Link port lines with the battery contacts.
    The Gamecube gba link is providing 3.3V, which is exactly what 2 fresh alkaline batteries provide (1.65V*2).
    About the amperage, the label on the back of the GBA says it requires 350mA, which i guess the GC is able to provide too considering the gamepad ports are supposed to power the rumble motors...

    Side questions:
    - do you know if it is possible to access the GBPlayer menu when using a GBA as a controller? (there is no "Z" button)
    - can i remove the GBA LCD and still power on the console?

    You can remove the LCD and power on still....... not sure on the rest.

    AA batteries only provide 1.5v, not 1.65... so you may want to add a small resistor, since 3.3v is 0.3v too much.
