Hi there. when playing around with my new Retro Fighers pad I found a key combination on the controller that takes you back to the start of the game or back to the DC bios if you press the combinations again. press L+R+A+B+X+Y+start all at once and it will take you back to the start of the game and back to the DC BIOS if you press again. Note that not all games I have tried will take you to the start of the game, instead straight to the BIOS.
Is this commonly known?
