What is this?

The idea of the freewing interface is to provide a way to connect the PC to your Action Replay (AR) or Gameshark (GS) cart thru a parallel port when there is no extra ISA slot on your PC to fit the comms link board.

The chain would look like this:

PC parallel port <-----> Freewing interface <-----> GS/AR <->PSX

5 vdc power supply -----------^

If you have an Xplorer cart you do not need this.
