mgs prob

I downloaded metal gear solid for the ps1 for the psp, so i putit all on andall that . When i loaded it up the poploader list came up and i chose load from flash ( or something like that ), then the message came up and then the playstation logo but then it goes black and wont go further. Is it because i chose the wrong thing on poploader. On final fantasy 7 i chose 3.72 and it works fine. What can i do ??
oh and my software is 3.90 m33


Also on my downloaded nba 08 when i go to season and go to start a match the game freezes and turns itslf off when i bought the psp i got3 discs of games and whn i play mgs portable ops it freezes when i go bk to campbell, any idea why

buy hard copies of the discs and dump them yourself...

so ithas nothing to do with the whole popsloader thing i chose cos i chose 3.72 on ff8 and it freezes in the opening video
