I understand this is an old thread, however...
Has anyone looked into using a mega button mounted on the front of their virtual pinball cab so you can continue to do the proper hip-checking to "tilt" the game? I'm thinking perhaps behind a front plate. Wire the buttons independently, then use button combination presses for tilt left/right/forward. Feels worth experimenting with.
I guess you could use it with adult arcade titles as well and call your cab Bump & Hump

The only reason I consider the premium cost over four microswitches is the potential for the high impact tokerance being handle in their design and not having to come up with a less expensive DIY alternative, but I haven't fully vetted a DIY variant yet.
I can't imagine anyone else who grew up hip checking these things in bars gets the same thrill from having extra buttons on the side of their v-pin.
