Well, it's been a while since I've been able to do homebrew on my PSP. Just downgraded it today and upgraded to 3.40oe-A. I am absolutely clueless as to how to work things, especially ISO games. Is there any chance someone out there would be able to link me to a walkthrough, or just tell the steps to me? I'd really appreciate it. Thanks!

hook up your PSP to the computer and you'll see a folder called "ISO" and you just put your iso file in there... that is it!

if you do not have an 'iso' folder, then format your memory stick

You can also make the folder manually.

Homebrew goes into PSP>GAME150

MP4 movies go straight into the VIDEO folder in the root of your mem stick

Also, OE fw has an inbuilt Devhook, so delete your ISO loaders.
