I'm not sure if anyone is getting this too, but I recently upgraded from my japanese psp1000 1.5 > 3.03 OE-C custom firmware and immediately put games in the ISO folder. Some of these files don't even show up on the memory stick, but if i format the mem stick and put the cso of the game that previously didn't show, it would be there only if there were no other iso/cso files there. So basically if i had .cso A,B,C,D. I put A, then B and all is good on the psp. I once put B first then A and A wouldn't show up. I tested C and D respectively from a formatted mem stick and they worked, but after trying to put A and B on with it, both A + B didn't display under the mem stick. So basically I can't put all 4 together and this baffled me because it wasn't a corrupt .iso/.cso issue. I can't resolve this issue. It's not a memory problem I still have 200MB remaining if I put all of them on... it just doesn't display all my .cso. And yes I have my "no-umd: disabled," also i have a umd in the psp and it's set on 1.5 kernel. Any help would be appreciated.
