Runing Signed Homebrew on the Vita

Post by PHtmlP241 » Sun Mar 04, 2012 1:21 am

Why dose this not work?. Here is what I did, unrar a signed psp homwbrew, copy it to C:\Users\XXXXXXXXX\Documents\PS Vita\PGAME\XXXXXXXXXXXXXXXX. (I am using open cma if it matters) , then I went on my vita and went to copy the game and it showed the game as corrupt data. My gusse would be that its cause its missing a psn licence file or that it wasn't actually a signed homebrew. Maby I should try a few moar.

Assuming you are running the homebrew through VHBL, you need to ensure the homebrew is in an uncompressed .zip format named install.zip, and placed inside the folder of a PSP savegame (though not the savegame VHBL needs to run.)
If not, this is because the PSVita cannot run signed PSP homebrews.
Also, signed homebrews do not have a license file, they are encrypted in a way that is perceived by a PSP as an eboot that was made by Sony.

ONLY savedata can be copy to vita directly. Others must be download from psn. "xxxx\Documents\PS Vita\PGAME\xxxx" only save the backup of PSVITA.

The Vita and CMA add an additional layer of signing/encryption.
This is why you cannot use Media Go to copy to your Vita, and this is why Signed homebrews cannot be installed. Basically, if you didn't get it from the Sony store, it's in the wrong format.

As an exercise, you can try to copy a PSP game from your vita to your computer, and see what it looks like.

We wouldn't be bothering with VHBL if it was possible to copy signed homebrews to the emulator in the first place :)
If you need US PSN Codes, this technique is what I recommend.

before reading wololo's post I though maby the ps vita was looking for a licence file cause all psn games have them,

I though it might have been a because we can kinda thing, like when work on hbl continued after homebrew signing was possible

At the time, work on HBL continued because there was no PSP (L)CFW for 6.39 and 6.60 yet, and because some signed homebrews do not function on PSP OFW, but can run when used through a signed HBL.
Signing for the PSVita is an entirely new thing that, currently, we cannot do.
