Help out a Confused Newbie

[Bustacap2K1]

Thanks Charlie,
I've been reading around and found that Messiah can load a DVD-R by just putting it in, same with other games. Sorry to bother you again, but I just have a few more questions to ask:

1. You can put in both CD-R and DVD-R backups and play them without swapping. Correct?

2. Do you need a GS2 w/ Messiah?

3. Where do you get Messiah?

4. Is the installation about as tough as the Neo2.2 installation? How many wires does it have?

5. What's the deal with Messiah clones?
