Thanks for your reply.
I'm now begining to think that it's not what I first though it was
that is causing the flicker.
Obviously because it's a game everything is done off a loop (except
all the other stuff I need to be sure occours at the right time
I.E. under interrupt).
The flicker seems to occour when I briefly go over 1 vbl in the loop.
The first thing I do after a vsync in the loop is scroll/switch screens
using the STE hardware scrolling. I think it's at this point the flicker
is occouring but I can't see how a flicker should happen. Surely
just the screen update would slow down.
Maybe I should change the screen refresh from 1 vbl to 2 vbl's and see
how I get on with that.
