Swap magic is a device that hacks the ps2 and makes it think it's playing an american game, the reason for this is cause the reason you can't play JP game on US ps2 is because ntsc code on the disc, think it stands for (national security code). But either way yeah, it's an illegal software in america, only place the buy it is ebay, there's one bid ending today if you want to try and get it. Search under video games on ebay and search swap magic 3.6 or just search swap magic, since it's illegal it might have been taken off so no garrentee. If you need more help with it ask and I can tell you how to use it.
