I know I have been away a while, but Playstation chipping questions?
If i remember right the Play station one is a simple pic chip and a bit of soldering, about 10min job, it is based upon model so check carefully you are following the right procedure.
Its all over the web as to how to do it, if it is a PS1 you want to do and cant find anything on how to do it, PM me and I will try and dig out the info for you.
Playstation 2 you can buy addons that will chip these from a lot of places on the web, dont think any soldering is needed for this one, but not to sure, never done a PS2
If you have any decent computer fairs near you they normally do it while you wait for £30 like Bowlers in trafford park or you could try checking this site out if you wish to try it yourself http://www.xbox-scene.com/tutorials.php
