It looks good on the emulator, but produces a rolling picture on my PAL TV.
This is a problem, that a small number of TVs seems to have, when the
vertical syncronisation isn't done like

STA Wsync
STA Vsync
STA Wsync
STA Wsync
STA Wsync

If you don't wait for exacly three scanlines or access any of the VCSs
registers during those three lines, the TV can't sync correctly.

There was a discussion about NTSC TVs having the same problem in RGVC
recently, so I think, it might be a good idea to change that part of
your code.
