I am wanting to play back ups, but I don't know which way to go. Mod chips seem the best, but I don't know how to solder. Swap disc, and flip top cover, seems good, but I heard it doesnt play all games. Hd also sounds good, but it still can only hold so much. I believe I have a version 7 ps2 model #39001. So which option is the best? Is there a way I can sodder without using a soddering iron, like clips or something.
