Hacking No more chance to install adrenaline?

[UltiNaruto]

The license is generated when the demo is downloaded to the PSP.

I have done this method with the Wipeout Pulse demo, so I can confirm it works.

He said .vpk not .pkg so the license wouldn't generate aka you can't use it. And even if you would have a .pkg it still not guaranteed it would generate a license since the license is made through psn. Unless PS3 has some sort of way to generate licenses from installed pkg.
Not sure about PKG installer on PSVita though.
