Well, if you guys have PSP 1000-3000 model and in any chance doesn't use the UMD (because you all use memory stick exclusively), do you want to do something on this unused UMD slot? I would rip it if I could but this space would be perfect for something else. I have extra memory stick but it would be unwise putting it right on the case because it would be damaged. Maybe the slot could be used for memory cart holder? And I saw someone use the space for extra battery. We could use for a tutorial. Any idea?
