Running iso's via USB

i can access pictures/mp3's with usbhost fine, but when i open an iso file it says "instert disc". do i need to change something around in config or what?

is that through IRshell? i've always wondered how you do that...

yes it is.

lol you always wonder how to do alot of stuff. Im wondering the same thing though cause i have the same problem the poster does

ya i cant ever seem to do anything with IRshell...

me eather, nothing about irshell ever works how its supposed to for me

Do you have a game UMD disc in your psp? I think thats what it's asking. And yea iR Shell is a little confusing.

i have the ISO file ON my computer, i have no UMD for the game. how do i run the iso file?

Stick in a UMD game disc in your psp and see if it works.

try going into the recovery menu by holding r as you start up your psp ==> configuration ==> umd mode and us either the sony np9660 -no umd- or m33 - no umd-

you can do that without going in recovery mode, just press select in xmb, but yeah I have the same problem as the poster and ive tried that it still doesnt work. Ill try putting in a umd even though its not the game I want to play and loading the .iso file of the game I want.

i dont think i have ever pressed the select button, hmm...are you having ir shell automatically start from the plugin mode or turning it on from the xmb?

mine personally starts up on it's own.

Okay after reading on http://www.irshell.org I figured out that even with the no firmware cheak patch loading a .iso file with irshell on cfw 3.90m33 isnt possible unless you have a dump of some of the flash 0 irshell files from a 3.80m33 psp.
