Cool. Sounds neat.

Yeah, I keep putting little expansion things on the stuff I do, but I don't
think they ever really get used. Having RAM and everything out there is
really best if other people would develop code for it, but I suspect that
wouldn't happen anyway. I'm inclined to just drop it for now.

True. Did Asteroids/DLX/LL use NMI? I have that easily accessable on my
board-- could use that to interrupt and save a game to RAM actually. ;-)
Otherwise I suppose we could just put a check for P1 Start in the main loop.
Pause if P1 Start is hit during the game...
Actually, maybe something like "Hyperspace + P2 Start = Menu" would be cool
too...

Yeah, I'm not 100% sure. Going from memory, I thought that POKEY's inputs
were connected to the dip switch block for Asteroids Deluxe settings. But,
if the code relocation goes OK it'd be easy to have the games read settings
from the NVSRAM anyway and use the menu program to set preferences.
