Okay, I downloaded a disk that allows you to swap games. Its origionally a DVD thing to launch DVDs but you can launch games too, which is how I load burned PS2 games ( I own the origional

). When I open it, the screen says something like DVDregionx or something like that, so look it up. What it does is take over your boot sequence, so that the PS2 realizes a game, THEN you are free to do what you wish. Dont think this will help, but thats your boot tool.
