The Godly Brother Mod will, in fact, mess with the mod. Plus, the mod now has cheats already in it. Start with a fresh game, untouched, and install the FFFox Mod following the directions correctly. Test it by opening it and checking the title page (should say 1.5.4 under my fox icon. After you've confirmed installing the mod correctly, you can add on Kagura's uncensor patch and daseson's color mod.
There is a Kagura compatibility patch, which allows one to use the saves from steam. And you can technically use any font so long as you rename the font's internal name to 07やさしさゴシックボールド and replace it in the Data folder.
As for the translation, about half or more of the mod's version is currently my translation, rather than the fan translation (so a 2nd fan translation technically), but I'm currently also modding it so that one can freely change the text to be whatever they want. Someone has even already mentioned wanting to start changing it to the Kagura translation, so you can keep an eye open for that if you really don't like my or Shadesishere's translations.
