Okay, I've got it now.

I had to swap the Vx and Vy labels in the process.
Now my cars move very similarly to the jets in Combat, so I'm pretty sure
the table this page spits out matches some code in combat somewhere. The
end result is that up/down is exactly 1 pixel per frame but left and right
are slower due to the aspect correction. I also have a problem where it
looks like 1 frame out of 256 it "stutters" when moving up and down which
might need some kind of special-casing. I think a lot of games have that
glitch, btw... It looks familiar.
I'm leaving it decimal since DASM can handle it fine.
Check it out.
I'm not signing the bytes because I add or subtract based on the rotational
index value. That way maybe I'm getting a bit more accuracy out of the angles.
It's about time we had a tool like this so we don't keep reinventing the
wheel :)

Just use the Windows calculator, multiply your result with 256 and
convert the number into hex.
