Transfer arcade high scores and system favs?

[floodie]

Hey guys. I have a back up of my 3TB build for obvious reasons. If i implement this build on a machine for my son for his birthday how do i :

1) keep the same favourites that have been added throughout all the systems within the main wheel? (Do i just copy the entire Data folder over to the back up?)

2) how do i transfer over the arcade high scores that we have battled against on the main house cabinet?

thanks alot
