I just bought an IPAQ 3765 with Pocket PC 2002 and the buttons appear to be mapped in odd ways. The insert coin (inbox) button seems broke. On all games it brings up the config menu (which I do not appear to be able to edit). On some games, when I exit the config I have a credit, and on others, nothing happens. The calender button does take me back to the main mame menu. Any ideas?
