This is a tutorial on how to ROM hack very easily. It covers decrypting, editing, and rebuilding. There are other tutorials, but this one seems to be the easiest. No .rsf's or scripts. It requires 2 PC applications and one 3DS application. If you already have Xorpads for the game you're editing, either by illegally downloading them or from a previous attempt at ROM hacking, you can skip 0:07 - 2:15. That's the xorpad generation part.

The video is pretty straightforward and shouldn't require a written tutorial. I didn't cut any 'obvious' steps out, everything is there in a 6 minute video.
