what this does is, well it's an eboot that displays the pngs in the photo folder, everything you do on the psp makes it react different, it *COULD* be exploitable but i am unsure as of yet. but i do need some help on getting it even further than it is now!
ok i made a read me for it and its all set...
1. extract the "IEUA HACK" folder to the games folder on your psp memorystick
2. go to games folder and look at the eboot file..(dont start the eboot)and just watch the *********. *OR. goto step 6*
3. after your psp freezes or seems to be froze press any button but triangle.
4. after you push the any button not counting triangle. the psp will freeze after sound. (psp will only make a sound if you key tones is on)
5. turn off your psp. then turn it back on.

*UPDATE*
I got bored so i made a new version.
i made a new edited pmf file which has sound. (its sonys pmf white start up screen) but with edited ASCll string to screw up how the pmf file works.
theres new pngs as you can see on you pc.
i used the pmf with sond so all of you have a better way of telling how long it takes the eboot to freeze for you.
the pngs were coded to blow up more pictures.
they might have the answers that you're looking for
