You can download premade NUS3BANK files at http://www.brawlcustommusic.com/. Instructions On your PC: 1.- Extract the Cafiine server files somewhere. 2.- Create the following folder structure in cafiine_root cafiine_root\[TITLE_ID]\vol\content\sound\bgm replace [TITLE_ID] with: 00050000-10144F00 for USA version 00050000-10145000 for EUR version 00050000-10110E00 for JAP version 3.- Put your song files (with extension .nus3bank) in the newly created bgm folder.
