Well, if anyone finds out about how to do this without modding the console, i would love to know too! Got so much game downloaded on PS3 and xbox 360, i would love to case them and having a dvd that i could install the game from at anytime!
Just the way content manager works with the Vita, i just back up the games to my computer and connect the vita whenever i want to install it back.
But this time, with a dvd for ps3/xbox! Would love that, i'll also do some research on this!
