No matter what, only the audio file X01.brstm or the Melee menu music is played on the menu screen. I had implemented my own music and the first file works but not consistently. Out of five times I load the menu screen, maybe one to two times it plays X01.brstm. The Melee menu theme is played all other times.
I find this odd considering all menu audio files (X01.brstm, X02.brstm, X03.brstm) are my own custom songs. These files were all created the same way, so I don't think that the brstm files themselves are the issue. Any insight?
Additionally, it seems like I'm not the only one experiencing problems with custom audio. Sometimes, the song from the previous stage will carry over to the next stage. I was playing Final Destination (N64 Version) and that music played again on Metal Cavern, replacing the normal Vs. Metal Mario theme (whatever it's called). This problem and the one I reported above persist with reformatting and a fresh download.
