Hi there! If you really wanna run emu's on your psp, then you need to do a couple of things: Buy the USB cable for the psp-to-pc connection, and a VERY FAT memory stick duo card; and you do not need to install the drivers if you're up to date on your windows updates. Also, make sure to check your psp's firmware and see if it's version 1.50, and if it's higher than that number, you're out of luck! Luckily for those of you who have unintentionally updated your firmware to 1.51, there's software that can down grade it back to 1.50; I think one of them is "Sei PSP Tool" Now, I'm using a 512MB card, so, I can stuff a good amount of games in mine. Just know that the larger your card is, the more games you can upload to it. Okay, you'll need a program named "Kxploit" to help translate & upload the Eboot.pbp file, which is the emulator, to your psp. It doesn't matter which folder you decided to keep the roms in, you can tell the emulator where the folder's at. Here's something that I want to warn you all about: if you're only intention for having a psp is to play emulators, then DO NOT play any newer UMDs that are psp movies or games. What happens when you play these newer UMDs is that they'll try to automatically update the psp's firmware, and you don't want that to happen.
