Creating an IPS patch

Hello,

I am planning to translate the english version of Pokemon Firered to German so that it can be used with Romhacks.
The only thing that is stopping me from starting right now is how I convert the translation into an IPS patch. I do not want to translate the whole game in Advance-Text only to figure out I would have needed to work differently to make a patch out of it.

Thank you for your help
