I'm trying to make a LayeredFS plugin that replaces the music in Miitopia, and having some difficulty. In romfs:/cmn/sound/stream there are the .bcstm files for the music. I used YATA+ to convert the .wav files I wanted into the .bcstm files, and renamed them to the right file name. Then, I moved them to my 3DS's SD:/Luma/titles/[titleid]/romfs/cmn/sound/stream folder. When I load the game, and load the battle (I replaced battle music) the game crashes. My replacement is smaller than the original .bcstm so it's not a case of an oversized file. Does it have to be the exact same size or am I doing something wrong?
