Ok don't yell yet guys but here is what I found at http://forums.ps2dev.org/viewtopic.php?t=4336

Seems reliable and good news for homebrew !

"As you may know, EdisonCarter has made a trainer for GTA that uses a straightforward exploit in the game to execute arbitrary code. He chose not to reveal his techniques, but with the new savedata encryption and decryption routines at http://forums.ps2dev.org/viewtopic.php?t=4335, now anyone can run homebrew on 2.0, 2.01, 2.50, and probably 2.60:

Decrypt the GTA cheat device using the savedata/decrypt sample
Find and modify the code (look at offset 0xc4 for the offset of the start of MIPS code)
Reencrypt the save using the savedata/encrypt sample
Note that the syscalls may be changed from the 2.0 VSH mode, since a different set of modules is loaded. Hopefully it shouldn't take long before someone clever like Fanjita can make a decent loader for us."

dude like 10 other people have thought of this...including myself and apperently it cannot be done because it is a whole different type of coding system/files...i mean its only save data!.

plus i dont think you can access all the necesarry files through the savedata because the game is running...but im not sure

Hi,

well as another website has just put this news ("Homebrew Coming to 2.01/2.50? ") on its main page (don't know if I can name it but it is http://pspupdates.qj.net), I really thought it was reliable. Who knows ?
