Ok, I have installed chips in the Playstation1 and the N-Gamecube(Qoob-pro). I do not have a PS2 yet and am going to get one along with a chip. I have a choice between the Version 7 older fatty..or the newer Grey thin PS2(V-15?). Q1 What version should I go with? Q2 What model is easier to install/solder a chip into?...is there a big difference? I remember something about desireable ports being removed in the newer models or something...and something about the built in IR DVD remote sensor. Q3 Any advantage to go for a certain model there? I'm debating over the DMS4 Pro SE chip and the Crystal Pro v2.0 SLE Limited from Mod-Chip.com Q4 Any obvious reasons to go with one over the other? Thanks for the help in advance..and if ya need some GC advise...I'd be happy to try to help..
