solder point questions
 

i'm modding my 5th ps2 with a duo 2 and ran outta wire all i have hooked up is wires pwr,rst,z , x, s decided for the hell of it to just see if browser comes up with only these 5 wires and sure enough it does but won't boot any games just wondering what exactly are the Z, X, S wires?

Well the 'S' wire is actually the scex point that patches the PSX games. 'X' is just one of the wires that patch the CD/DVD controller. And I believe that the 'Z' wire is like RST but linked to eject.... I might be wrong about that one though.
