yy-chr and the like can easily swap around colours in palette data, but can any editor/tool/script swap actual colour data in a .chr file? Ie. take all pixels with colour 0 for example, and all pixels with colour 1, and swap that info?
I did a search on romhack and here on the forums but couldn't find something like that.
