I've got a small problem, I've jailbreaked my PS3 and installed Backup Manager. Even downloaded a couple of games, but since my BluRay-laser is broken, I wonder if there is any way to bypass the "You need to insert a disc to use this feature". Any help will be very helpful
No, not possible yet. You need to have one disc present at the time so it can emulate the loading function but maybe in the future someone will develop a emulator that doesn't need a disc present. Just sit tight and something will pop up, you've waited 3 years so far won't be long there must be someone working on it.
