They should appear as a bunch of folders that start with "extracted" in the same folder as the toolkit and the rom. Though if you have the wrong version of packhack it won't create any folders for some reason. (I don't know how to get the right version, I had a friend help me with that)

It should be possible to run on Citra. You can unpack the rom with HackingToolkit3DS, which will create the files necessary for following the randomizer's instructions. After you're done randomizing, you just gotta replace the old files with the new ones and then rebuild the rom.
