If I am in a jackpot, or just regular play or something, and the hopper runs out of coins, will simply opening the door and filling it be it or will I have to reset? It wouldn't make much sense to me If I have to reset and stop the jackpot mode for a friend of mine or something. I have seen vids of the actual parlors in japan and when an error occurs, they just come and fill it up. I feel like in a parlor if they had to stop their jackpot mode because of the hopper emptying would be quite unfair. Thanks!

EDIT: I also figured out how to pick the reset lock, so I can turn it and reset, but its very tedious and annoying whenever I get an error.
