I found out how to add and change card sleeve in YGO Simulator or even YGO PRO. I went to YOU TUBE watched and then did change card sleeves. This is how - First copy any YUGI card sleeve and save two of the same and must be a jp jpeg files, or turn into jpeg. Then go to simulator and then right click open file location "DON"T Run it. When you open file location look for textures, click open. Look for the card sleeves inside, they should be the black ones. "NOTE" how these show cover and cover 2. You click and hold moving both to your desktop. The copies you make "MUST" rename to cover and cover 2""""" Remember you need 2. You then click and hold and move inside where the black covers where. That is all, and the background and other items can be change, but I have not done that.
