NGPC's hidden "D" button

A fellow named FluBBa is making a NGPC emulator that runs on GBA. It's pretty slow right now (download the beta here), but along the way he discovered something very interesting - an extra bit in the register of buttons, that when pressed, actually activates debug modes in certain games. This is different from the debug mode found in Sonic, but more on that tomorrow. Not all games have been tested, but so far three games have been shown to have interesting results when the button is pressed. They are Card Fighters' Clash, CFC 2, and Dokodemo Mahjong.

Flavor, who did the CFC 2 English hack, kindly sent me some screenshots of all three games, including CFC2's English version, which has odd results because it's already been hacked. These were taken using a modified version of his own emulator, RACE. If you want to see the pics of all three games, download them here.
