You can also choose to show or hide empty cells (note this only applies to the viewing mode within the tool the actual Mugen setting is not affected). Other options allow you to hide the top layer while dragging a character around - useful for some motifs where the grid is partially hidden. The program reads from mugen.cfg and the f file of the selected motif, and tries to scale the screen accordingly it should get it right for Mugen 1.0 but for hi-res WinMugen you need to use the setting available via the File -> Options menu. It should work with WinMugen, hi-res WinMugen and Mugen 1.0. Hopefully this demonstrates the basic idea: To give an idea of how to use it, I've made a short video. I've had a stab at rendering the select screen as accurately as I could, though it's not perfect in particular the alpha blending is only an approximation of how it looks in Mugen. It's a new tool I've been working on to enable editing of your Mugen select screen using a visual drag&drop interface. Hopefully some of you will find this useful.
