Well if your runnin 1.5 it works fine. To find it just serch IR shell in google.
But if your running OE firmware Im almost certain that is does not work! I've persnally tried it myself on 3.03OEC twice and still cant get it to work under 1.5 kernal.
I got a folder named pspirshell31 which i unzipped and found different folder and some other things inside. The folders in it are : IRSHELL, devhook046, PSP, (2 differetn text document called) install and the other one called Revision History. I also go two different adobe acrobat documents called: User Guide and the other one called FAQ. what and which folder should i install first?
ok, copy the IRSHELL folder to the root of the memstick. then u should see another 2 folders within the zip archive called PSP and devhook046. go into the PSP folder then go into the GAME folder and copy across the 2 folders called irshell150 and irshell150% to the GAME150 folder on your psp (if u have custom firmware - if not they go in the GAME folder)
I dont know what you mean by firmware but if you mean what is my current psp version. Let me tell you that it is ver. 3.02. wiil irshell still work if my psp is ver. 3.02?
