I tried using Roxas75's theme editor but ran into several issues. First, the only download link available was extremely slow (despite using Mediafire, which typically works fine), and I had to use wget to download it. That's not really an issue anymore of course now that I have the program, but the program doesn't even work for me. The Import and Export menu items do absolutely nothing, and when I try to open a body_LZ.bin file, this happens:
The console window that appears says something like "The system cannot find the path specified." And unfortunately, there isn't even any source code so I can't tell what's wrong. I heard somewhere that spaces in the path can cause problems, but there aren't any spaces in the path at all. I even tried moving it to a folder in the root of my C drive with no spaces just to make sure, and it gave me the same problem.
Has anyone made another editor I can use?
