That was the only thing I did. Downloaded a few saber fonts from saberfont.com and put them on the card.

Is there ever a time when the visit to Saberfonts has you leaving with just the one?

Simply too many to choose from.
I really hope that the task of formatting the card works. When it came to the die settings being correctly assigned, was it responsive after these changes? Other than Fonts, I've never found the need to overwrite anything else or even enable the Aux-Twist function for colour change. As I run a 6/6/12 Setup, the method I use when 'tinkering' is manual field/data edit instead of via the Config. Editor. This is what I was shown and what I have been following. I know
HotRod and
Snakeeyz99 are regulars here and run RGBA+ Setups as there are others that are more familiar with SC2 Board, hopefully they can chime in with some assistance also.
