I've been researching how to use a slidecard on a version 9 PS2. From what the instructions say, there's a screw in the corner of the tray along with clips or something on the sides. My version 9 doesn't have either. However, my friend's version 3 fits that description perfectly. Anyone know how to get the cover off on a version 9? One other question, do I have to use the real card, or can I just use a credit card or something? I see it has a notch to latch onto a hook to pull it back on the slide back. But on my friend's V3 when I use a credit card, the hook goes back into place when I push the tray back in. I'd be greatly thankful to whoever answers my questions. I've been looking everywhere.
