personally i would HIGHLY reccomend the o2
It is damn simple, good for a fist time installer
IT IS ONLY PAL (unfortunetly) so if u are a us citisen then dont even bother
I chipped my ps2 successfuly well ... the 2nd time (i melted a few ribbon cables ... (rolls eyes) the first time)
If u are pal i reccomend it, i may be a bit biased tho ... it is the only chip ive used :P
Matrix infinity does seem a popular solution so if u are us, id prolly go wiv that, dont read alot of complaints about it ...
DMS 3/4 ... well as far as i can tell is an ok chip, apparently it is big tho, so its hard to find somewhere to put it ...
As far as i can tell the makers pissed off alot of people (alot on this forum) by stealing code that wasnt theres, and not giving credit where credit waz due
P.S. i had never modded anything b4, barley had any practise at soldering .....
It is not easy, and everything is alot smaller then it looks in the pics
