A buddy of mine wants me to look for a mod chip for his PS2 so he can play the psx ddr games. I'm looking for a good solderless chip. I'm not sure which version system he has, but it's older. Does anyone have any recommendations for a reliable, easy to install chip? Also, any site recommendations of where to get one? Lots of the sites seem pretty shady and I'm not really jumping to send them my credit card number and address. Thanks in advance.
