NEW in core 3.0:
This is now LoRes only offset, ULA will have it's own registers $26 and $27 (to be added to wiki) (also it's not 100% clear to me if this split did happen already in the version delivered to factory, or it will happen in the following bugfix update, but it should eventually happen).
