PSP iso files that refuse to work

I have 3.03oe-c and i have tried placing some psp and psx games on my system. i have tried with the umd in the slot without and using the NO-UMD option in recovery mode configuration. it won't work. the code is 80020148. please help. much apperciation.

well if you have a disc in and have no umd turned off.. then i think its just a bad iso.

Are you putting the files in the right folder?

I often got the error, just switch the kernal it uses (boot into recovery mode it will be somewhere around there)and also some iso's won't work with 3.03, but work with higher versions. Is it only certain iso's or all iso's? If it is all iso's then try the kernal thing, if it is just a few then they made be incapable of running on 3.03OE-A. If you really want to try it, you can upgrade to a higher cf and it MIGHT work. Also make sure what DA said is true^^

Here's a quick rundown:

All PSP's ISO and CSO game file goes in the ISO file [C:PSP/ISO <- in the bolded text]
All PSone games goes into the Game folder [C:PSP/GAME <- in the bolded text]
-----
If you are using the NO-UMD function, try to take the UMD out of its tray when loading up an ISO/CSO.
If you are going to use PSone games and it is not working (freezes at the XMB)... make sure you are not messing around with your opening_plugin.rco file in the flash0 folder. If you are messing around with your opening_plugin.rco file, try to find the original file of opening_plugin.rco.

(if you do not understand what I am talking about.. let me know)

Make sure your using a game or game demo umd disc, movie umd's wont work.

what he said I remember when I first tried to load an iso I had a movie instead of a game and nobody ever mentioned this to me I just keep trying other settings and stuff. That was in the days of devhook though.

ok. i think i've got it. this was my first attempt at running iso on my psp i probably screwed up. could someone link me to a tutorial as well i was searching and couldn't find one. all of you advice really helps. much apprecitation!

What PSPortable said is probably the only info you need. Just repeat with his instructions.
