A while ago I wrote on encoding using sub-bit resolution.
It just occurred to me WHY I needed to do this on the NES - it was involved
with creating a password for a large game, so that the player could come
back and rejoin where he/she left off. There were quite a large number of
parameters that needed to be saved/restored, but it all had to fit into 6
LETTERS and a few punctuation marks (eg: EP-NZE). That gave very few bits
(30, to be exact), and sub-bit encoding was therefore a great idea.
By the way, I remembered coz I need to do it for my 2600 project :)
Cheers
