manually editing prefs for old intuos in Ventura, anyone know which files?

I've got a couple of intel mac minis with intuos 3s attached to them, I've just updated to Ventura and I got one of them working with the 6.3.15 driver. It didn't want to work until I copied the prefs in \~/Library/Prefernces/Tablet from Big Sur and overwrote them and then the panel acted normally with mapping and switch assignments. Both systems are dual monitor, but the second system is a bit more complex. The overwriting trick isn't working so I'd like to try to manually input the mapping or de bug the hang up, but when I change the preference panel I don't see what files are getting modified even when searching system and invisible files with terms like "map" "switch" etc. Anyone know which files hold which prefs?
