ISO/CSO Problems

Olowkik · 07-11-2009, 06:39 PM

Everytime i'm trying to run iso's or cso's in my psp 3004 i get error (80020321).
it shows the game icon but it won't run it.
i have tried three different games 1.NFS Most wanted(CSO) 2.Fifa 09(ISO) 3.Socom(ISO)

I'm running Custom Firmware v5.03 GEN-A (Full) with chikhen r2.

any suggestions on what the problem could be?

I dunno if that chicken shit you're running supports ISO/CSO's but if it does, you need to switch your UMD driver. Go the the VSH menu or boot into recovery and switch the driver to M33. I don't even know if your firmware has the M33 driver though. If it doesn't, try Sony NP9960.

Press "Select" in the XMB. It might be "Home". I can't remember.

you can't use m33-6 you have a 3k use this File Details-Custom-Firmware-Enabler-v3.51-PSP-Homebrew-Applications - that will install most of the features of m33 and you will be able to change your UMD driver
