Front end recomendation for a dedicated trackball cabinet?

[virtuallyunlimited]

Hello all! I am in the process of building a dedicated Trackball only cabinet and am looking for advice on front ends.
This will be the 5th or so cabinet I have built so am familiar with a bunch of configurations but I have not found anything that seems to support the trackball as a contol input to the front end.
Does anyone have any suggestions?

I have run MalaFE on a bunch of cabinets and recently played around with RertroFE. I also built a dedicated driving cabinet using Checkered Flag as the front end.
I would like to have the visual addons and look and feel of something like RetroFE, but would love to have the trackball be usable to navigate the games.
The Control panel will have the track ball, P1 and P2 start and credit buttons, then 6 configurable buttons (all separate inputs on an Ipac). There will be no joysticks.
Mame will be the primary emulator used, though if I can use AHK or batch files to launch some PC titles that would be great as well.
I can always fall back to a button only front end control, but it just seems like a miss to not have the trackball usable in the interface on this type of cabinet.

Thanks for looking and any recomendations.
