ROM Hack Looking to get into 3ds rom hacking - Best tools to start?

[BossRoss93]

Hey all,

So I ultimately would like to try to hack Tri Force Heroes to allow for two players. But of course, I need to start slowly and build up to that. So I was wondering if there were some basic tools to help me get started? I just want to get to a point to where I can unpack a game, and get into the guts of it and see what I can do. I can't seem to find a catch all guide for that on here, so if there is one, I am sorry.

Thank you!

Here you go

note: at the beginning it says you need firm 4.1 to 9.2
Ignore it if you have A9LH since you can launch decrypt9 at boot
