| Short Description | ShortDesc::Pixel offset to use when drawing ULA or LoRes Layer. |
bits 7-0 = Y Offset (0-191) (Reset to 0 after a reset)
LoRes scrolls in "half-pixels" at the same resolution and smoothness as Layer 2 (0-191).
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). (I will update + cleanup this over time as I will be able to verify all the info)
