Hacking About the R4 screen

[shadowkillerdrag]

When you go to play the ROMs there is this weird red circle in the upper-right of the touch screen. I was just wonder what its function is. Because wen i press it, it turns green , press again it becomes red , etc.
So what does it do o.o

That's the reset function. If you press L+R+A+B+X+Y while playing a game, it will "reset" the R4 and will take you back to the games menu. That way you don't have to turn off and on your DS to play another game.

RED: Disabled
GREEN: Enabled
