I have not found a great way to setup VPX & VP9 table to coexist together via PinballX.
Tried adding it as other, but menus seem funny.;
Best I found was to just keep them both in one database and manually add the below to the VPX versions in the .xml database file:
<alternateexe>VPinballX.exe</alternateexe>
Works great, but the only issue I have is when I run an Import Ratings via Game Manager, it erases all the non-standard script like the above, thus have found to just no use the Import Ratings option for now. Also, since in the same database, I only get one graphic/icon for the system (VP), no way to really see a diff of VP9 and VPX versions from the PinballX menus.
Any better fix?
Would be nice if PinballX supported multiple versions of VP within Game Manager instead of just adding VPX as an Other system.
