You only have to save your file as bmp in paint, because FantastiCoast does not accept jpg. https://www.simtropolis.com/forum/messageview.cfm?catid=120&threadid=117322&enterthread=yquote> SC4 does render jpgs which is why all of my earlier fantasy maps are jpg grayscales. @ Gold_Panda94: Irfanview [an image program] can used to make your jpg an 8bit grayscale.
