PSP 2.5 Firmware Cracked
Category: PSP | Griffith
Wow, this was quick... apparently some guys managed to override the PSP Tiff patch implemented in the 2.50 firmware by using a modified save game file

Tradional PBP and SAVEGAME Layout
-ULUS100xxxx or EBOOT
--Param.SFO (tells how the psp handles the file: e.g. title - update ver. 2.51)
--icon0.PNG (icon)
--icon1.PMF (almost like a short movie clip <500kb
--pic1.PNG (background for pile that appears when you look at the file)
--SND0 (background sound-not in most saves or EBOOTs)
--Data file/data.psp (name vary depending on game saves...data.psp is the name when in eboots)
--Data.psar(only in eboots)

Well my Exploit contains...
--Param.SFO (tells how the psp handles the file: e.g. title - update ver. 2.51)
--icon0.PNG (icon-overflow.tif)
--icon1.PMF (blank PMF found in iso rip kits)
--pic1.PNG (background for file-framebuffer)
--SND0.AT3 ( small randow sound clip)
--Data file/data.psp (from v1.5)
--Data.psar(from v1.5)
and...
--Pic0.PNG (overflow.tif)

My Original Idea For The Exploit
1)the icon0 would be set to the overflow.tif
2)pic1 the framebuffer image
3)the 2 data files as 1.50s data files
4)SND0.AT3 a music file >20mb
5)ICON1 the blank pmf found in iso rip kits
6)Param file set to be read as updater version 2.51
7)pic0 overflow.tif resized to 272x480

Only one thing from my original blueprint wasn't used : the AT3 file is 5kb

How This Works
This works by overloading the psp audio with a glitch sound, and overloading the image handler with overflow.tif, thus in conjuction overriding the TIF patch.

i wonder if that would work??

as i said: its not mine. so i dont have any of the files or any links. someone should really try this.

THIS WAS NOT MY IDEA IT WAS "GRIFFITH" 'S

I heard about this potention exploit about a month ago, nothing came from it if i remeber correctly. And Tromedlov was asking for the link to the original news article or forum, here it is:

http://forevergeek.com/psp/psp_25_firmware_cracked.php

And to prevent any problems from other sites, it was not Griffiths idea, Griffith is just the dude at Forever Geek that posted the news article.

The original post in the PSP3D forums is dated the 13th November 2005, so they've been working on it for quite a while, and nothing has emerged yet! If someone else wants to trawl through 31 pages, be my guest, you can get to the forum from the ForeverGeek page!

Cheers,
