The program is Graphics Editor which is a super mario world oriented character editing program. However this also happens with YY-CHR a more popular and universal character editing program. Here is also a collection of .bin files and palettes for you to test with. Thanks!
Hi @MM102, I tried to run those programs on a VM but the Graphics Editor contains a virus and I wasn’t able to know how YY-CHR works. Just in case if you can save the clipboard format using a program like Clipbook Viewer in .cl7 that will be help us in my side to give it a try.
