I have version 4.01M33-2 on my PSP, and just downloaded Radiant Mythology 2. It's saved as an .iso file, and is in the ISO file on my PSPs root menu. Whenever I go to Menu > Game > Memory Stick, the only things that come up are Desperatar del Cemeneterio, a file that came when I made the magic memory stick, and the file that's supposed to be RM2, but it's coming up as corrupted data.
I downloaded it, converted it or whatever with uTorrent, then unzipped it with 7-zip. I checked many guides, and had help from a girl who's done this before, but couldn't figure it out. If anyone could help me, I would be so grateful.
first off you should go ahead and upgrade to gen-d that way you will have newer game support. secondly, you will have to format your card, and the copy the iso into the iso folder. give that a try. if you get an error code, then you will have to upgrade to play that game.
i updated my psp version to 6.20....all games saved on my memory card dont appear on my psp...i cannot play my games..how can i play iso games on my psp again???
Make sure your memoory stick is formated as FAT, then create a folder named PSP in the root of your card, and a subfolder named GAME within the PSP folder, put your .iso there. If that doesnt work I would reccomend updating firmware.
