Ciao! I see that in Core A there's an included driver for Cotton, but only for the rom called "cottong.zip".Hello
Someone knows with which core Cotton is playable?
I ve tried Fba core but it is slow with sound issue
Also, make sure to use the rom from the Mame 2003 plus romset. Fba and the various Mame versions, all use different romsets.
Rom sharing is forbidden here, but if you google for "mame 2003 plus romset" it will be very easy to find.
