Well, let me put it this way. I have two psp fats, one with cfw 3.40 OE-A and the other with cfw 3.90 M33. They both have this iRShell icon under the psp xmb game icon menu. I'm not quite sure what this program really does but I have browsed thru the program, trying to figuered it out. Any additional information would help out since this program does not come with instructions.
