Pony Fantasy VI Remake

Did you also try patching a clean, vanilla, ROM? It might be a conflict with changes made in your mod.
What version of the ROM are you using? FF3us 1.0 or 1.1?
Did you compare the patched rom with an unpatched rom, to make sure it patched ok?
What are you doing to test for changes?

Here are some IPS files, try them just to eliminate the possibility of xkas error.
These put the new code in $C266F0. The N file is for nonheadered roms and the H file is for headered.
