Is there any possibility of you releasing just the decapitalisation component of your patch as a standalone thing? Wichu's patch is nowhere near as comprehensive, and there's no Fire Red version of dkp's patch for Emerald in the ROM Hacking Resources thread.
Hi there. I don't suppose you'd be able to whip up a patch to undo the font change to your ROM base? I prefer the Fire Red font, and my attempts to do it myself didn't go so well because I can't find the version of Diego's patch you used.
Update: I managed to find out how to fix it from Diego himself - copy 0x34A50 bytes at 0x1F3100 from a vanilla Fire Red ROM to the hacked ROM.
