Nero priority and dummy files
 

Hello,

I burnt the game marvel vs. capcom 2 and it seems to work and load fine. I remembered afterwards that I did not change the priorites in nero before I burnt the game. So I have 2 questions:

1.) What exactly are the importance of dummy files and the order they are burned?

2.) Should I re-burn the game? Is the a hazard if I do not?
