Though again, driving controllers aren't easy to come by.
If they're easy to read they'd be a nice addition, however.

Again, at the risk of sounding like a broken record, what's the 
estimate for how long it takes, in machine cycles or scanlines? 
Because moving it to, say, the Overscan (assuming you're not 
needing that time for game logic) ISN'T a matter of fine resolution,
since you can spend all your dang time polling for the charge; it's
the risk of not using the full range of the paddle, e.g. the thing
hasn't gone off so you just say "outta time, just call it maximum"

I guess this weekend I can try whipping up some sample code. Maybe I
should tell Al to put some of my royalties towards a stelladaptor or 
two...(I think I've budgeted spending my royalties like 2 or 3 times's "paid" for my hotel in Philly, part of my iPod, some gaming 
gear at Philly, etc etc ;-)
