Need help running ISOs

Hi,
I'm running 3.40 OE-A Custom firmware on my downgraded 1.50 PSP.

I can't seem to run any PSP ISOs. I've tried putting them in all the folders I can think of (ISO, GAME, GAME150, GAME340) and no luck. I just can't see them in the XMB when I go to Game/Memory Stick.

I've tried several different ISOs from different sources, so I don't think it's a problem with a faulty ISO. I even tried a CSO.

One of the sites I downloaded from gave these custom config settings, which I applied:

Recovery Mode > Configuration
Autrun program : disable
Use No-UMD - DISABLED (Remember to put a UMD in the drive)

Recovery Mode > Advanced > Advanced Configuration
Plain Module in UMD/ISO - ENABLED
Execute BOOT.BIN in UMD/ISO - DISABLED
Use isofs driver also in UMD-inserted mode - DISABLED

Any ideas?

btw. I did get a PSX eboot.pdp to run.

Your supposed to put iso's in the ISO folder. But im guessing your problem is that you said your running 3.40OE-A on a 1.50 psp? How in the world does that work????? Its either 3.40OE-A or its 1.50. It can't be both unless your using devhook. Please specify what firmware you have and we can help you more. Make sure the ISO folder is in the root of your memory stick.

Ah, sorry. I tried to give too much info and just ended up confusing things.
I am on 3.40OE-A, but I got there via downgrading to 1.5 first. That's what I meant.

Anyway, you've already sorted the problem for me. The ISO folder was in [Root]/psp. I've moved it into the root of the memory stick, as you suggested, and the ISO's are showing up on the XMB.

Thanks!

Okie dok your welcome. Lol kind've confused me there. But downgrading to 1.5 is basically the only way to upgrade to 3.40OE-A, other then using 2.6 and the eloader which is rather...old.
