DEVHOOK 0.46, DOWNDATER 2.71, full pack, and much more, on one site!
I'm just a user, and found this little hungarian site, so I thought, i share it with you. There you can find every application (in full pack) to run the 2.71, on 1.5, for loading your legally bought, and dumped UMD-s, of course, only for speed, run the Browser or downgrade your 2.71 psp, if it isn't TA-082..
Have a good time!
On the left bottom of the site, you can find the english translated version, but it isnt really needed i think.
