Hmm, now I'm worried. I've run it on StellaX, Pcaewin and z26 (as well as a real console) and it seems fine. However,
I have just moved a bunch more code from the Vertical Sync into the Overscan. I had had this problem earlier, particularly
when the Saucer was onscreen in later stages of a level (It's more calcs to draw less Instigators), but moving Saucer
code into the Overscan seemed to solve it. Maybe I didn't quite move enough?
Anyway, I'll have the final-final posted in a bit...
