Well, i use swap magic CD and the biggest game I have is Gran Turismo 4 which is a DVD9 game. I use it to swap games and I recently bought it to see if it will work so I can swap Dvd's better. But when I got home and tried it on swap magic CD it won't load it, it just sais invalid disk. I thought that the game was big enough so I can swap games with it but it just says invalid disk and I don't have swap magic DVD unless someone can put it up for me. What can I do now?
