I know for a fact that I've seen a few (hardly any) PS3 game isos that say once you install the supplied patched Eboot.pkg file, you'll be able to play the game straight from the XMB (no dongle nor backup manager), on systems that are NOT jailbroken. At least I think that's how it works. Just a couple of questions: 1 - Does this mean I can have a JB PS3, get the game all working nicely, install the Eboot.pkg file, make sure it works via XMB, then update to 3.70, and still be able to play it via XMB? 2 - If not, what the heck is this for then? 3 - If so, is there a known list of games that can work like this?
