Thanks for all your responses. I recently got a email back from the company that I bought the mod chip from. They say that the DVDr's will only work if I use Gameshark v 1.9 Does that sound right? Also, I've looked at the CD that came with the gameshark (in the very hard to read area on the CD). It seems to have 2 different version numbers which is kind of confusing me as to which version of the gameshark I actually have. Here is exactly what it says:
Playstation 2, Gameshark 2, Version 2, Americas 1.99d
Sorry for the stupid question, but does that mean I have version 1.99d or version 2? If I do have version 2 are they correct in saying that I cannot use this gameshark version to play DVD backups and will need to purchase version 1.9?
To answer the previous question on the bottom of my PS2 it has 4 screws covered by little rubber coverings. The case didn't actually come completely off in order for me to put the mod chip in, I had to semi-bend the plastic covering up a little to put the mod chip in. I see what I think are two screw holes inside the expansion bay. Sorry if I'm looking in the wrong area for this
