1.50 homebrew

It was discovered in June 2005 that unsigned code could be run on a firmware with version 1.50. The discovery allowed early US PSP adopters to run homebrew which quickly led to articles appearing in the mainstream.[1]

Two ways were developed to run unsigned code, swapping memory sticks, and later, a safer exploit known as 'KXPloit'.

[edit] Swaploit

Swaploit was released on June 15, 2005. It was created by a Spanish team and involved swapping between two memory sticks at the launch of the game, before it crashed with an error, to run the selected homebrew. There were reports of failing memory sticks using this method, but none have been verified.

[edit] KXploit

KXploit exploited a misuse of the sprintf function of the PSP by having another folder named exactly the same with a percentage sign before the file name (eg game and game%). The percentage folder contained no data aside from images and a PARAM.SFO. The folder without the % had only a DATA.PSP, the file containing the code. The problem with this exploit was that corrupted data would show on the memory stick (as well as the normal data). This was because the PSP would only see the program that had a PARAM.SFO file in it, the file inside the % folder. The file with just the program data would be seen as corrupted. However, this was shortly overcome by using two tricks. One would exploit the FAT16 system of the memory stick, and the other involved putting __SCE__ before the name of corrupted folder and %__SCE__ before the name of the normal folder (with the percentage sign at the end removed). Both tricks would remove the corrupted data, because the non-% folder would be invisible to the PSP, and still allow the EBOOT to be run. Many tools exsist, like PSP Brew, Sei PSP Tool, and more, that automatically hide the corrupted data and organize your previously installed programs.


I just need a file called PARAM.SFO
DATA.PSP and __SCE__ ,%__SCE__

What are you actually trying to create

[xcjzerox]

trying to play around with the folder and see if any homerew could could work
and could you please gave me the files for gpsp I already have the bios

[splodger15]

What bit dont you understand

Homebrew does not work on 3.01

Whatever you are trying to do will not work

[andrewgabriel77]

the sprintf function was patched in 1.51
the next exploit came with 2.0 and the eloader/tiff exploit via the photo menu...this was patched in 2.01
the next exploit came with GTA:LCS through the same method used with the Cheat Device in said game, this only worked up to 2.6 and only with the first run of GTA:LCS games
the most recent exploit is in the libtiff exploit...again this is with the eloader by noobz and Dax's Homebrew Enabler, this only runs up to 2.8
no other homebrew has been exploited as of yet

Right now your best bet is to stop upgrading your firmware until the coders catch up and find an exploit for your firmware version...in the meantime you can enjoy ps1 games (if you have a ps3 that is) as well you can play all of the commercial demo's and you can use the flash enabled web browser to play flash and java games
