Another 1.51 Homebrew (3 Mem Sticks)

Post by mvpo.geo »

IM sorry to just post these 1.51 homebrew ideas that I find from other sites but its because the people at these sites and I myself don't have the proper equipment...this time it being 3 Memory Sticks...
THis came from a guy named Bulls84 at psphacker.com.....GOOD LUCK Im hoping some how this works..................
Oh! ok, nvm. I just found out that the 1.50 hack works with 1.51. Just do the following:

1.Do the same stuff as the 1.50 hack.
2. Creat a new folder inside Game, call it MS3.
3. Extract DATA.PASR, save it as EBOOT.PBP.
4. Put it in the MS3 Folder.
5. For 1.51 users you need 3 MS, not 2 MS.
6. So MS1, then MS 2, last MS3. Don't get yourself confused. Cuz I did the first time.

Thanks to all my friends thought of this,

the ELF* execution is disabled from memory stick on psp with the firmware 1.51 and 1.52 you can load only the ELF from Ram.

*by ELF i means a elf non crypted .

Read the starting post, I don't have the equipment, meaning I don't have 3 memory sticks but it seems this is false. I am sorry if it seems I am posting alot of "Possible 1.51 Exploits" but I just want to get this thing hacked.

when you consider that homebrew apps don't have a data.psar, it's false immediately.

The reason swapping works on the PSP 1.5 firmware (among other things) is that the firmware will allow the execution of processes that are not encoded. It still requires signed/encoded/encrypted executables (EBOOT.PBP) that pass the tests. Hence the swap trick was born. Swap a 'valid' EBOOT.PBP for the invalid EBOOT.PBP and poof, unsigned code on 1.5

The PSP 1.51/2 firmware does NOT allow for the execution of non-signed/encoded ELF binaries. It also (AFAIK) rechecks the initial program on a memory card swap.

This trick will not work. Even if the above was false, the memory card reads the file at two specific points: One is when you hit X to start it (which verifies the signature and begins to run the code) and two is once the logo disappears and the code is started. Switching a third time would have no effect, and could potentially corrupt a valid memory stick.

IMHO, worthless idea for a 'three stick swap'. Don't try this, you'll probably end up with a junker memory card unless you have a PC to reformat with.
... anyone up for some l33th4x?
