[Coco] CoCo 3 under MAME

[Salvador Garcia]

I installed MAME and it is working, sort of. No problems with the CoCo 1 and 2 emulators, but the CoCo 3 screen is duplicated inside the MAME main window. The CoCo screen on the left is a dull green and the one on the right is the typical brighter green.

What I enter in one automatically duplicates on the other, as though they were mirrors. Has anyone had this behavior?

Thanks! Salvador
