Unfortunately I can’t help with a solution but I have exactly the same problem (using V31 Stable). The tables load up fine. The camera and tilt controls work but nothing else (inserting coins, starting the game, flippers etc) works. Tried remapping controls etc but no luck at all.
I tried switching to the 32 beta but Future Pinball just crashes with a serious error right away.
Would love to get this fixed as it’s one of the emulators I was really looking forward to.
