ahhh , NOOBS

and also if u dunt have a real game put the umd to no UMD required it should work man and like asddasit said you need a real game to run iso's

So the problem is because I'm not using a real game?

OK after getting a 100 game there is only one that worked on both modes UMD required and no Umd and that is FF war of the lions!!
lol I don't know why this game particularly works fine.
so should I format the flash0 with pendora or something and is there any safer way cause I heard that the battery or the memory stick may not work after that.
I know guys I've been annoying U but I'm really a noob and I don't know anyone that have a psp that can help me except U.
Thanks alot

hmm this is weird then maybe its wear your getting them from pm me and tell me the site of where your getting them from i can suggest some good ones to you too but i dun see the need to use pandora on your psp

Thanx my friend I sent a PM to U , but I got one question : If the game have something wrong would it give me a black screen and the loading from ms will stop?
cause I tried a lot of different games from different sources and all of them gives me the black screen!!

The problem is solved , guess what was causing it?!!
The MEMORY STICK lol
we never thought of that,but I began to supect it after transfering some song to it and the songs is not visible on the psp .
so I went to the store that I bought the PSP and the MS from and traded the MS with another one cause both are still in the guarantee period.
I don't anyone to be tormented like me so If that problem happens to anyone its the MS.
And thanx to all of U guys for trying to help me.
O and the videos are playing perfectly now
