Do you have a PS3? It is not crackable yet, but someday it can be. Anyway, according to the afterdawn website, a modder took it upon himself to mod his PS3 by installing a switch. What this ultimately does is load swap magic, then flip the switch to spit the disc out, and then you put your backed up PS2 game into it.
Please note that the swap switch mod is only good for 1st and 2nd gen PS3 consoles due to the PS2 backward compatibility. The new PS3 for 3rd gen and above is ditching the PS2 backward compatibility, so the switch mod will not work.
