Ok I see what you mean, but those are differnt things. You can't drive two different types of monitors from Groovymame -currently- at the same time, as it would be the case of the lcd marquee setup type. However you can have two different monitors attached, and configure groovymame so that some games run on one of them and some on the other, e.g. classic low res games on the arcade monitor, and modern high res ones on an lcd or pc crt, everything without having to reconnect wires , etc.
