Well, I just bought a PSTwo with Bemani, and I really want to play the JP versions. So, now, I'm in the process of finding the right mod chip. I really wish I knew someone who could solder, but I don't, and I don't want to risk killing my PSTwo. So, I'm only looking at the swap method mod chips/CD things. Do any of them let you run PS1 AND PS2 back-up games? I only see the PS2 ones. Any help is greatly appreciated!
