Ah....u kiddin yrselves. Sony know that a bit of piracy is good for sales of the ps2. Thats why it outsells the gamecube.
As for modding......More tricky than the version 7 cos of the vias but to be honest if u could handle a version 7 then u should do this no probs. The only problem is B-I connections on the vias. U might need to use something to remove the coating on the vias before u can solder onto them. I use a scalple blade to gently scrape the coating off but I wouldn't recommend it.
