Well I installed this non-solder DMS4 EZI Pro chip in my PS2 over the weekend and totally screwed it up. The PS2 isn't recognizing the mod chip for some reason and I can't get PS1 games to boot up anymore. Don't think I damaged the motherboard though since I can still play games on it. I read that the inability for it to play PS1 games though is do to a bad "x wire" connection (whatever that is).

So yesterday I shipped my PS2 out to a pro modder to finish the job for me and solder the chip in. Hopefully he can get my PS2 modded and working without having to do any major work to it. I got the chip for almost half off for what it sells for but after screwing it up and shipping it out to get professionally installed, it would have cost me the same if I just got the solder chip and sent it out to get modded in the first place.
