The Padapter is an interface for a SEGA MegaDrive/Genesis 3-button game-pad, so it can be used with the Commodore VIC20, C64, C128, Amiga etc. It is inspired by the Open C64-MegaDrive Pad Adapter. All buttons on the game-pad are de-multiplexed and usable by the computer. The adapter also provides two switchable mappings to help with games that use the joystick up direction for jumping.
