That does seem unlikely--otherwise I would just assume that it was using VBL polling.It switches out the middle of the screen to text, and animates the top and bottom in LORES. IIRC it just uses the white bars on the screen as switching points. Now I misrembered the problem - ][ scanning works fine, but //e scanning doesn't. All the timing is NTSC. I did have PAL timing working but not switching to that at runtime.
That makes more sense. It's probably using VBL, which is not implemented.
But on my PAL //e it _did_ work fine. Can anybody tell me if it works on an NTSC //e? (Flicker is failure.) Cheers, Nick.
