This how it is done the GA9ES has 3 extra board 1 being a program card the other 2 are the S-video card with extra parts mounted the same is with the video card. I purchased these at a total cost of $100, revoved the old card's and installed the new ones. The ant input was directly soldered to the board. Then removed the jumper, quite an easy job.
I hear you ask the warranty well if some thing goes faulty open the case swap boards over then take it to get repaired. Nobody will ever Know.
