I don't think it is possible to play PS2 games on an un-backward compatible PS3 without involving emulation. It must be the ability to play PS2 backups on PS2 compatible PS3s. It should not be different for debug firmwares as at least one of the PS2 chips must be included to play PS2 games, the "emotion engine" (ps2 cpu) or "graphic synthetizer" (ps2 gpu).
i am new to the ps3 scene, but i have a test/debug console. i have been told that it will play backed up games, is this correct?
The only thing is that it will not play the latest games as it wont update, is this normal?
