Pony Fantasy VI Remake

Yes. In addition to the Lion armlet and Umaro ones, I've also applied patches for the Doom-Vanish glitch, the Rippler bug, and Psycho Cyan.

I'd definitely start over fresh than. Usually the patches will say in the readme, if there is one, or on the author's site which ROM to apply the patch to (header or not) But with some of the 1st generation older ones, like those, it will not. Patches these days will usually come with options for both, and very good readmes, but years ago this was not the case lol.

And make sure if you do start over fresh to get a clean version 1.0 ROM. I can't remember if you knew that already.
