ok, i jsut bought a PS2 used, i unsure which version it is, but i know its serial number starts with U0, its date code is 1A and it has 10 screws on the bottom. Also, once i know what version what is the next step in getting a modchip, if I know its version 2, do i have to find a version 2 modchip, or will one of these universal ones work. Once a modchip is installed, will burnt copies of games run easily or am i expected to have problems loading and running? if you use a slide card or boot disk, do you still need a modchip? does it matter what kind of DVD burner i use to burn these games? i understand theres a DVD+R and a DVD-r, whats the difference? thanks guys.
