RUSSIAN SOFTWARE and real ZX

[VELESOFT]

помоему лучший основной стандарт - писать так, что бы работало везде

Yes. This correct writed software can work also on real ZX machines

This is very necessary point:
If IM2 vector table will move to fast memory area then game will playable on all ZX models/ZX clones without screen raining effect:

FIX for best software timing:
All very fast routines can be move also to fast memory - games will work on real speed.

Software can't crash if software run on slower ZX models/clones. (problem with interrupt and critical timing routines)

PROBLEM WITH PORTS:
All extra ports(features) must be disabled if original ZX 128/+2 models is detected
