I asked this a while ago and while screenspain does the job, it doesn't explain -how- it works.  mikro (formerly from mystic bytes) actually wrote a videl guide that explains the chip and how to program it low level ...

I really must sit down and learn some 680x0 code .... but anyway:

http://ihrisko.org/~mikro/docs/mikro/videl.html

but I see Pang is already done so maybe I am too slow!? :)

cheers
