So looking at the arcade setup doc's, it shows that Atari 2600/5200/7800 are to use MAME as the "wrapper". I can not get it to work and was wondering if there is some instruction out there that I can't find to help me get it working:
Attached are the 2 screen shots. 1st is the clip from the setup doc, 2nd is my setup on MA.
Any help would be greatly appreciated.
