Ah, that is a lovely controller, it is almost as complex as a cabinet to set up, but the good thing is the config is standardised and you could do it step by step by following this:
https://github.com/3DPTronics/VirtuaTilt/blob/main/Configurations/VirtuaTilt-SetupGuide_v1.3.pdf
The core of it is the KL25z, which is a controller board for cabinet buttons, toys that are controlled via DOF like the solenoids and shaker motor, it has an accelerometer for nudge and I believe has a potentiometer to measure the plunge, which I’ve never installed in my cab. There seems to be a control board for things like service menu, coin door, etc.
Edit: I’ve deleted the original paragraph that was here. Baller will install the following, so I think it’s worth checking if you’ve installed any of this already. If you have, I’d uninstall and start again with baller and use the linked manual above to do the config at each stage where it’s relevant. Baller doesn’t install dof, you need to do that separately, but I have no experience of installing dof first, which you have I believe, and then vpx, that in itself might be worth reading around.
