AtomicFE did that , when the credit management from the FE was activated. You could choose freeplay or not.
But for the same reason than the coinDrop program , i decided to not make this feature available at all.
But i should come back soon with this feature , but in another shape that could satisfied the ones who are against this feature.
Because if i well understood , MAMETeam is not against credit management from a Front End, they are simply against the exploitation of MAME . So if the exploitation becomes impossible with my new version , it should be ok. I think.
