Naulsheets work as long as they're 2 folders away from the data folders, CharSet is a data folder for example.
For example, the Naulsheet files should be placed a directory away from RPG_RT.exe.

If the Naulsheet files aren't 2 directories away from the data folders, or you don't want to use Naulsheets you
should choose not to use them when the game prompts you for your choice.
