Ok...I had a PSP-1000, with a memory card with just about every old system's emulators other than the PS1 and Atari. The emulators still work on there just fine. However, the start and volume buttons started pressing voluntarily, and when I start the emulator, other directional buttons began to act as if another direction were pressed. So, I went on ebay and purchased a modded PSP for $29 that is firmware 6.37. They said in the description it was a PSP-1000, but it turned out when I got it to be a 2000. However, it didn't come with a memory card like was implied in the description, and I plugged in the one I was using for my PSP-1000, and all of the emulators are not working. It says "data corrupt" on the PSP-2000 I just bought, while when I try the same memory card on my old PSP-1000, the emulators work just fine. What on earth could be the problem? How can I get these emulators working ok on my new PSP-2000 so I won't have to go through the trouble of returning it?
