Well, it makes a lot of sense, but I hadn't seen the technique
described before. Do you think, then, the way 8 bits completely holds
the maximum range of distortion plus frequency is design or
coincidence? (And if design, why couldn't they just use a single
register for both?)

Also, with a "normally working 2600 driver", is there a standard way
of indicating "rest"? I was using $FF to indicate "turn volume to
nothing", but that wouldn't work with the 5.3 technique. Does it have
a "magic value" that doesn' come up in real life that can be used as a

Yep, that's what I described...right now Tune2600 outputs a decimal
value for distortion, and a decimal value for frequency in seperate
columns, so I could grab those and add them together hex-wise.

oops, meant to erase that.
