How do you randomize Pokemon Sun/Moon for Citra?

Apr 11, 2017
Hey guys,
So I wanted to play a randomized version of Pokemon Moon, and I downloaded the proper ROM for the game. It's already been decrypted, so I went to extract the files and edit it. Once finished, I go to rebuild the .3ds file, but I can't seem to figure out how. PK3DS refuses to build the file because "The number of RomFS do not match with the original game!" and 3DSBuilder builds the file, but it doesn't work. If anyone could walk me step-by-step though the process of properly extracting and then rebuilding the .3ds file, it would be very much appreciated!

I used PK3DS to edit the files, and PackHack to extract them.

    I might be wrong on this, but I'm pretty sure you need to decrypt your rom again once it's been repacked with 3DSBuilder.
