There are quite a few 'Variants' in the Event Editor that are not listed.
For example CopyTiles Variant E4, and E5.
One does the CopyTiles and 'remembers them' IF Battle/or Menu Access occurs...
the other, 'forgets them' and tiles reset (but the gfx of the tiles don't update on their own, leaving that part of the screen will update the draw however)...
In either case, the CopyTiles are reset after leaving the Location. Places that seem to 'permanently' change areas via CopyTiles are simply done with Events and mem.addressing.
......
Anyways, if anyone knows what these Variants to Event Editor Commands, they should also post their findings. Thank you.
