How to auto-boot game when PS3 is started?
Solution 1:
There's an Disc Auto-Start option under Settings > System Settings that sounds a lot like what you want, but that won't start it when you turn your PS3 on, only when you put in a disc. It used to behave like you wanted, but they changed it to the current way in update 3.0. I don't think that there's any way now.
