I'm not exactly a modder in the sense of programming, so I would recommend checking out the community Discord for Golden Sun modding for specific modding relating questions. While the Discord is closed, you can find invite link on the forum's homepage.

Overall, in the modding scene, I mostly focus on Golden Sun projects. A lot of that focus specifically with GS 1. Though I've also done a couple Paper Mario projects on the side. You can see the full list of projects I've done here:
