Currently it's going quite well. The LedWiz board which controls the output of the lamps, contactors, shaker, knocker etc., was easily deployed and configured in Visual Pinball.

Three buttons are configured for "Start Game", "Extra Ball" and "Exit". The coin button simulates the coin insert. And pressing the plunger causes an "Enter." 

Here is a short video and a picture of the button setup:
