As you know, in conjunction with Neo2.2, you use AR2 or MM+ or DVD Region X as the boot disk to load a backup behind it. For AR2 you will need the card that comes with it. I use DVD Regin X as my boot mechanism. You would need AR2 to boot DVDRs.

We've got MM 16 but don't use it. You end up being dependent on it just when it won't boot a specific DVD-R game. That's why the good old Sony 8MB jobs are best.
