I got a regular PSP at version 2.71. I want to downgrade to 1.5 and then upgrade to 3.03 OE-C. I figured the easiest way to do this would be with wininstallers. So I got the 2.71 -> 1.5 downgrader full version from xtrusion found here: http://psp.xtrusion.es And the 1.5 -> 3.03 OE-C upgrader found here: http://forums.afterdawn.com/thread_view.cfm/460892 Questions: 1. So basically, all I need to do is run the wininstaller exe and do what they say, and I should get to where I want to be right? 2. Where do I put the files (it seems like there are folders set up where certain files likes games, movies, etc. should go)? 3. How do I customize everything? Thank you for your time and consideration.
