Not for me ; as a demo coder, timer C is used for anything (playing 
samples, sid sound volume variations, removing top border ,...) except 
using a 200 Hz system timer :)

By the way, my previous mail was wrong. The transition when looping 
doesn't imply going to $ff for a brief, but the data reg goes from 1 to 
the new starting value. Under specific cases, it's possible to read a 0 
in data reg though during a brief time.

More later after doing tests under Hatari.
