Thinking about getting rid of my PSX1 and get a PS2. Thought about just buying a used one or refurbed one. Are there any special model #'s to look for like in the PSX1? Also what is a good mod chip to get? I have about 40 cd-r games that i used on my psx1, those are playable on the ps2 with the modchip, right? Are the controllers swappable? Anything else i need to look or watch for? thanks for your help
