Here wo go. My psp is 1.50, and I want to upgrade to 3.03OE-(something). But I hesitate. Here's what I want out of my psp: N64 Emulator GBA Emulator SNES Emulator NES Emulator Maybe PSX. I'd settle for less. That's it. I'd like a newer version to play my newer psp games (that I bought lol) but its not a must. I guess my main question is do I lose any emulation options by going to 3.03OE-something. My second question is... what is the difference between 3.03OE-a/b/c? Third question, what do i need to play the emulators ive listed? Can I play the games ive dumped or do i need to download special homebrew games? If you can answer all these then... you are cooler than me.
