The programmer has come forward with video's he took of the prototype playfield as far back as 2013, appears the game was a lot further on than anyone thought.
Attract mode video from 16th December 2013:
Dev video showing operation of the top rollover lanes:
Testing of some motors on the aux coil tests in the service mode:
Finally, some game play video that i shot some time before i got the ramps, install them and made updates for their inclusion. Its quite a short vid and i don't really shoot much, but please appreciate that this was just another dev video for testing out certain features.
