Okay, I hope that's the case.  It'd be nice to find out if the NES is
even capable of a finer granularity, and if so, whether any games use
it or if it's just limited to demos that require precise timing etc.
that few or no emulators can run anyway.  I have a feeling that if it
can be made to work completely, writing more than one pixel per loop
iteration may improve performance on platforms other than the dc.
That's a big if, though.

Prices dropped to $99 from $149 a couple months ago.  It's very cool
hardware, though I'm not sure a scanline-based NES emulator like
tuxnes will ever run at 60fps, at least without major modifications.
But I am stubborn...

You can try http://mc.pp.se/dc/ as a starting point.  It's got good
info and links to other sites.  Also, you can

mailx -s "subscribe" dcd...@eg... < /dev/null

or the like to subscribe to dcdev, the dreamcast development mailing
list.  Archives are available through yahoo groups somewhere.
