Music Replacement

This page will go over on how to replace music in Super Mario 3D Land.

Basics
SM3DL bcstms are version. Most songs in SM3DL have at least 1 track and 2 channels per track (2 tracks and 4 channels can work too).

Tool
Citric Composer website.

Steps to follow:

 * 1) Open Citric Composer
 * 2) In the top tab go to "Tools" -> "Isabelle Sound Editor (WAV, STM)"(ISE for now)
 * 3) Go to top tab in ISE "Edit" -> "Import File" and select your audio file (use .wav)
 * 4) Now you should have channels in the channels *folder* under "Project info"
 * 5) Right click on "Tracks" and then click on "Add".
 * 6) Select the new created track and in the channels option add the last channels you added
 * 7) A stereo song would have 2 channels, which appear as Channel 1, Channel 2, (and would continue as we add more audio files) so we write
 * 8) Click on "Update Channel"
 * 9) Then in "Project Info":

Looping:

 * 1) Check "Loop".
 * 2) Change the loop start, end, original start and original end to whatever fits your song.

End:

 * 1) Change Version from whatever it was to.
 * 2) Click on "Update Project Info".
 * 3) Top tab "File" -> "Export Binary".
 * 4) Rename your file to whatever you want to replace, and you're done!
