I had a question about the swap magic disks and the slide tool. First of all do they really work with the tool or do i need a mod chip. If I do need a mod chip whats the best chip out for a ps2. I bought the disks and tool, and I backed up a game that was dvd based. I used the dvd disk and used the tool just as an instruction video told me to. to make a long story short, I could not get the back up to play on my ps2. I used Dvd dycrypter to crack the game. Please help!
