Okay, so now I'm 60% sure that it fully works, but I really do need testers! I've tried about 3 or 4 people, but a couple have some limitations on their Vitas (i.e. not being able to get an update payload, etc.). If you know you are on 3.52 or lower, and have an existing game which needs updating, then please let me know. :)
So yesterday, I finally knew how to make >3.20 installation packages, exactly like the Unity install package. (you can find some examples of the install packages in the other thread.)
However I made another install package, which I haven't released for obvious reasons, which was a Ratchet and Clank 3 install package (R&C3 is obviously paid-for content), and when I tested the installation package on my own Vita, the installation worked!!!
Now I'm wondering if that install package would work on other Vitas. Any suggestions? Would it work? Wouldn't it work?
Because I think it's only the PKGs that have the DRM flags.
Update! Here's a screenshot of it fully installing the Ratchet & Clank 3 install package onto my 3.15 Vita!
