Ingame control bug now sorted.
Having a slight problem with Mr.Spiv/Asmans blitter solution, one of the bitplanes flashes as you move, which i'm a little surprised at.
Its almost as if it can't redraw one bitplane fast enough before its called again.
CPU redraw routine for 68000 has a slight tearing issue at the top of the screen.
Going to see if I can reduce the overheads more.
