Could you use those "Y" connectors that the Coleco Gemini / 
Columbia Home Arcade (what I knew it as :-)  ) use, to use their 
combo stick/paddle controllers as paddles?  If not, and even if,
given the scarcity of driving controllers, I think Paddles would
be much more popular.  And any game that requires a hardware hack
to play is going to be a hard sell.

I don't think 30mhz flicker is the end of the world that you think 
it does, esp on a black background.  Maybe an "intelligent flicker 
routine" would be worth it, but w/ 4 objects, that becomes a very
difficult problem.  Well, maybe you could compromise, treat the cars
as two pairs, and branch to seperate kernals...still, pretty tough.

(I've had some side conversations about this; while a lot of the people
on stella are hardcore kernal wizards who love squeezing every last 
drop out of a kernal, I hope there's room on stella for those just using 
the 2600 as a fun game platform.  Obviously, work by Thomas et al. has 
really raised the bar of professionalism, and even the stuff later in 
the life of the 2600 puts my stuff to shame, but still...not every hobbyist
effort is going to be a kernal masterpeice.  Which doesn't mean we should 
slack on features, but it's better to get a *fun* game "out the door" than
to let a project languish in "it needs to look *better*" hell)
