Okay, this is how far I've gotten so far: 1. I downloaded the Prince of Persia gameboot (the one with 3 bloody slashes) and put it in the root of my PSP. 2. I downloaded PSPset and put it in the GAME150 folder, since it won't start up in the GAME folder. 3. Started up my PSP, Game/Memory Stick/PSPset v0.9, pressed X 4. highlighted "Change Gameboot" and pressed X. Then highlighted "Backup Gameboot". Nothing happens. Then, highlighted the option above it which says "Change Gameboot" and pressed X. Then, a row of "Copying Files" appears and rapidly scrolls down the screen. I click back, then quit. 5. Now, I load up a game (Snes9xTYL 0.4.2me) and the gameboot didn't change at all. It's still showing the PSP logo with a white background. What did I do wrong? Any help is greatly appreciated!
