What? Where? How? When?
I got a psp with firmware 2.81 and I would like to know if there is a way to downgrade or upgrade (or both ) its firmware in order to do all these happy things on my psp (emulators, shells, etc.).
Also if it is possible can someone tell me that if somehow I finally manage to to customize my psp, do I have to change these customization tools (shells, cracks I don't really know how u call it) in order to run different applications?
For example if I use the "A" crack to run the "AA" application can i run and the "BB" application too? Or I have to run the "B" crack first and then run the "BB" application?
Lot of questions I know
P.S. : forgive me for my bad english and in case u don't understand something or I am not clear pls say it and I'll try to rephrase it.
P.S.2 : Did I say helloooooooooooooooooooooooo ?
P.S.3 : And thank U
