tried a whole buncha stuff-
=exported it to psp via sei psp tool--didnt work
=tried to put it in an update folder--didnt work
but was does happen is that when you go to the mem stick to access it,the psp freezes..this could be a possible exploit maybe..but thats just a maybe b/ i have ver 1.50 as ive already said...also,when you do finally click on it--it sorta just stayed there for a sec on the screen...the loading symbol is loading in the lower right corner and then it says that the file cant be loaded bc of some kinda error--this may work on 2.5,who knows!?
