Btw, were you trying this with FreeMiNT? If so, Vsync() has another "bug", it's delayed because of the whole OS messaging system, i.e. it takes longer than on TOS.

Apart from that, it should work all right. Atari800 uses 100% XBIOS and works fine even in FreeMiNT. This function is called after each rendering: https://github.com/atari800/atari800/blob/master/src/falcon/main.c#L188

Basically it's doing what Anders & others recommended, setting the screen pointer (via Vsetscreen(), which doesn't want for VBL) ASAP.
