I've seen several AO maps that will remove the shadow for the removed Gate.
Those can be adjusted.
Watch for open Sky showing.
Those I need to flip the faces for.
All this so far is done in a hex editor.
The biggest difference?
The CRC has been adjusted to allow GrannyViewer to open it!
In SH5 the Devs for some reason, saw fit to exclude the CRC check.
I would like to think they saw limitations if it remained and did this purposely.
But I have no official statement to that fact from them.
I only bother to correct the CRC as it's much easier to work with Granny Viewer then Goblin.
GrannyViewer provides the information needed to edit things at the base level.
