Huh, I didn't have any problems setting up the DBA on my CCr. It seemed about the same as doing DBAs on any of my other pins.
Only trouble I ran into, was that in order to do 3 games for $2, I had to do custom pricing, since it wasn't one of the default pricing options. But it wasn't too hard to figure out.
What is hanging you up? Sounds like maybe you need to change the pulse settings on the DBA itself. You can make a dollar bill do 1 pulse or 4, and you should be able to adjust the game settings to work either way.
EDIT: What exactly happens right now when you feed a dollar through the DBA?
