Attempts improvements to video fetch timing. Alas, a lot of guess work here.

Improves contended timing.
Still not quite on the money, but this was an overt bug.

The implication seems to be of a fixed phase swing.
I'm enquiring further.

Lengthens sync, better to conform to PAL; experiments with fixed-phase colour burst.
I need to get hold of real documentation here.

Corrects address generation, ink/paper selection.
Seemingly to give a correct +2a boot. Time to add a keyboard and find out, I guess.
