How can I edit .amx files?

Hi, I'm trying to make a mod of Pokemon Sword where all enemy pokemon are dynamax, but from some testing I now know that the two main problems are:
-I need to make it so random trainers can also dynamax
-I need to make dynamax reusable
Being able to dynamax seems to be based on the location and not the AI, I gave a random trainer the same AI as a gym leader but still didn't dynamax but maybe there's something I can change about the AI to work around that, and maybe it's the same case for making it reusable.
The issue is that I don't know what I should use to open and edit files such as the AI files, which are in the .amx format. Any idea what I can use for that / how I can do it?
