Hi everyone, I'm new to the homebrew scene since I at last was able to downgrade my firmware. I downgraded using this guide: (the 3.03 tutorial) and then I proceeded to install the custom firmware using this guide: Everything installed correctly without any problems. The problem is that when I try to start an ISO file game or a ROM I get the "game could not be started" message. I've searched all around for a solution (that's how I found this website which is great by the way)I found a thread in here that said to go into the recovery menu and make sure no UMD was disabled...I followed those directions but I'm still getting the same problem. I'm also using ISO files downloaded from the links posted at PSP Underworld since I can't use Bittorrent from this location...those anyone have an idea of what could the problem be? Your help will be greatly appreciated.
