rupture

Thanks for all the useful information here!

There's also a simple Rupture splitscreen example here on CPC-Live which I don't think anyone's mentioned yet:

I used that to get started on ruptures but there are quite a few errors in it. The height of all combined ruptures (CRTC registor 4) should equal to 39 and the code does not do this and the timings are not 50FPS. But the upside is I learnt the fundementals from it so it's a good aid to get going.

The height+1 of combined ruptures should be equal to 39 !!!
