About time you got into TI-82 coding, Paul. You've done so much for the
emu scene, and the thing that has been lacking thus far for the 82 is an
emu (So, Randman made one.. but that's still in beta, as is yours). Keep
working on it.. we've had the tools to dump the ROMs for a long time
(since ASH 2.0), but no use for the ROMs.

Probably the most important thing to be emulated is the link, and possibly
the ability to load an asm shell. I'd honestly like to see the speed
brought to a level in which a 486 can run it at full speed.
