Quoted from Hondanut:
You are 100% right,also the MMR will have adjustable flipper strength
I guess I will have to continue to make due with my non-adjustable strength flippers that are hopelessly stuck on "strong" setting.
OK, that was a funny, but I actually have a serious question regarding this. To be able to adjust for low line voltage one would need to know what the line voltage is coming into the game. Does the game internally measure this and report back to the user when it encounters this situation, or is it expected/assumed that all end users will have a multimeter to properly measure this themselves? If it's the latter maybe the games could include a simple meter in the goody bag? If the flippers get weak it's a bad assumption to just crank a setting as there could be a mechanical problem that needs attention instead...
