Quoted from galaxian:Ah, i bet they are using the display frame ids to trigger the shaker. Cool. I hope colordmd comes out with a shaker addon.
On the renopinball stream last nite showing a MBr in action for 2 hours, they said it was a 'digital shaker' when someone asked about what kind of shaker motor was being used. Not sure what that means, but sounds like rarehero has it right.
