reset coin counter?

[Marsupial]

I got a coin counter with my gutted cab, and would like to reset it, and make it work with my coin door even if I am using MAME.

I am uncertain how it works, but also wonder how one would go about reseting it to zero?

There are plenty of threads on this. [Here] is one.

If you can't reset it, they are very cheap. The last one I got was 2 Euros.
