OK to end fear of the exploit, here are the inner workings:

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 dont know what any of that means but sounds good to me! this is all good information right? =)

Does this mean that going over the savedata in the XBM will trigger the exploit? Oh and BTW, are you guys only planning on getting a downgrader done, or will there be any attemps of running homebrew. Something else I'de liek to mention, a fellow named fanjita as been working on an eboot loader for 2.0 for quite some time now and has done a wonderfull job. Maybe the loader could work with this exploit, who knows.

I can only wish kernel mode could be possible.

hi guys i'm just posting to let you know that both exploits do work!!!

also if butterballer360 could PM me with what he intends on doing with this, it would be greatly appreciated.

What does it makes this exploit?
Nothing for the moment I guess...until someone give us the instruction and a way to downgrade...but it would be better to allow to run homebrews....

Good work!

it will all come with due time to produce somethin (like a downgrader), and when it does, i will applaude butterball and everyone at psp3d and those that kept the faith

So you managed to get the TIF exploit running on 2.5? DOes this include acces to kernel mode?

Doubt it. The 2.0 exploit doesn't, either.

hey everyone..
congratulations for this big step

I was wondering if anyone can write a guide to downgrade 2.50 with this eboot file? that should be a big favor for a newbie like me..

thanks in advance..
