It works in almost EVERY console.....
It boots DVD-9 games such as Xenosaga, 100% of the time...
Look at the boot procedures at the top of the PS2 forum (in a sticky post)....
That will also tell you some differences....
This is the Magic 3 boot procedure:
With the disk assumed in the tray and the tray closed:
• For PS2 games, power up normally from STANDBY with RESET button. A single tap is required.
• For PS1 games & DVD Movies, power up from STANDBY with RESET button held until the blue EJECT light comes on; then release RESET and the disk will boot.
• Please turn off the PS2 (to standby) before changing Mode (PS1/PS2/DVD)
This is the Messiah 2 boot procedure:
ALL games load just like a ORIGINAL....
Put the game in the PS2 and it loads....(Nothing Else to do)
