Not all MK1s have first edition written on it, the main things to distinguish MK1s are:
1) Game Pad (Picutred above).
2) No Korean writings on the left half of the back label.
3) Can't power low-power USB devices such as a thumb disk when you have a USB host through a cable or BOB, MK1s provide less than 5 volts.
well it doesn't matter, since it doesn't exist, right?
it's an int13 game called goldmine...they took the gp2x off their list of supported systems without much fuss...maybe a week ago? don't know exactly, just noticed it now. anyway this was in contrast to the large fuss they made about how they'd be devving for it.
