About FE4 Hacking

Questions
1

  • Hacking method: Nightmare (I guess)

  • Base Game: FE4 (Japanese version)

It’s just a small question about fe4 hacking.
If I want to make an customized version of fe4 with nightmare, can I use an English translation patch on the customized rom (after the changes) or can I just use nightmare on an already translated version of the game ?

Due to how nightmare actually works, it should be just fine to apply to english patch. However, Id recommend trying both and making some back ups justtttt in case.
