Hey, good news: NesterJ just booted up in my PSP!
Here's what I did: After converting the EBOOT.PBP, I put the other files in Nester's folder (the image, the .txt file and the .dat file) on the 2nd Memory Stick, together with the converted .PBP. Don't know if it really makes a difference.
So, umm, you followed the exploit instructions and managed to get you PSP to run homebrew, just like nearly everyone else today. What do you want, an award?
"Dear PS2dev.org,
today I switched on my PSP and it started playing Wipeout straight from the original disc.
