Okay I joined the game world 2 decades ago, now I got my first psp cause I was a fan of Nintendos new console world... DS Wii.. anyways another story to tell. I got my PSP Flashed by a friend from 2.80 oe to 1.5 then up to 3.10oe... good I can now play by backed up games, I have a friend that got a store that sells and buys used games, so I get to play almost alkl of the games and he gives me some good prices for the ones I want to keep. Okay now the main 2 problems. 1. I got my 4gb Sony Memory Stick and it works fine after killing my head all afternoon long, now the problem I have is that I can only load some of the ROMs (iso/cso) I have acquired from friends as backups AND of course I do have them as well on my UMDs... now I got DBZ shin budokai and another road, I cant get the another road iso to load at ALL. I got the shin budokai to work but not the other one, as well goes for Valkyrie profile, and some others wont load... but I can get the Killzone to work, good game... and the Need for speed carbon also to load... so I will like to know what to do to make the other games load, of course I have a UMD inside... I am noob but not that much For instance also I get a black screen with Metal Slug Anthologies... I really like the series, got all the games for PS2 and Wii Anyways any help will be appreciated.
