What am I doing wrong?

[SilentNight1647]

I recently installed cfw on my PSP and I read that I could rip all my games to isos and play them from the memory stick by copying the iso to the ISO directory I had no problem ripping them or compressing them and UMDGen recognizes them as the correct games so I am pretty sure the iso is good but no matter what I try they will not show up in the games list on the memory stick. I tried switching switching the driver to M33 and the other two but it still doesn't work. Is there a plugin or something I am missing? I am running 3.90M33-3 and I have tried everything I can think of. Does anybody have any ideas as to what I am doing wrong?

did you put the iso in a folder inside the ISO directory? that was the mistake that i made at first, you just have to place the iso directly into the ISO folder

I tried that, no dice I have three isos I am trying to use 2 uncompressed and 1 compressed and none of them work.
