Well I was hoping I could read up and find out myself, but I guess I'm just not that dedicated. I couldn't find it. I have a "SCPH-30001" PS2. I'm guessing that's a V1? It's sort of old. I've heard its possible to mod this with the correct chip, I've heard its impossible because it's so old, and then I've heard that it can, but not as well due to its inferior laser compared to v7 and past. I can burn a PS@ game no problem (as if it that was hard) but as you can imagine, it doesn't play. This leads me to want to mod my PS2. I researched a little and read that a DMS4 Pro, DMS4 Lite, Matrix Infinity, Crystal CC1.1, DUO2 SE, MarsII, Slide Card, and Slide Card Pro will work. Is there any truth to this? All this stuff is sort of confusing because I'm new to it. I'm OK with a soldering iron, but I'd much rather have a "solderless" one just because I don't have too much confidence in my expertise. (i.e. I cannot guarantee there won't be shorts, solder balls, and foiled up copper scrapings) If any of you could point me in the right direction of another thread/site that could help, or give me a recommendation on a mod chip that will work I'd be eternally grateful. Thanks.
