Well I know a little about computers (enough to build my own), but there is no way I would have ever figured this out without the tutorial. I knew how to do all the steps, but I had no idea what all the steps were doing. It's not that hard though....just time consuming...especially if you have to do it more than once.
All the work is done on the pc. When you get the final image ready you hook your PS2 hard drive into your PC and transfer the image to it. I'm gonna start transferring from my pc more because 1) I don't wanna kill my ps2 laser, 2)it transfers alot faster, and 3)it doesn't get read errors as easily.
