Neil, have you tried both the led, and lcd ?
What are the pros and cons of each ?
I want to emulate the original dots does the led do this ?
you mean in one colour or in multicolour?
I have put LED in all my games since it came out, its more pinball like and feels more like a DMD albeit in colour. You can run the DMD in one mono colour if you want. It doesn't do the dotsxl and other modes that the LCD does but even on the pin I have LCD in (Star Trek: TNG: Monster Bash and Spiderman) I don't user any of the modes anyway! The LED does suffer from the same unlit pixel display issue highlighted above.
