Key Changes:
► Added Coin Button: The L1 button is now used as the arcade coin button making MVS compatible.
► Pinout Disposition: The pinout layout has been rewritten to simplify the connection to the MVS board.
► Joystick Option Modified: Modified the R1 button to function as button A instead of the (X) button when L1 + R1 + Select are held for a few seconds. This is useful for Metal Slug and some shoot 'em up games.
