Cave Story has a variety of interesting music (in org format) that was developed by Pixel through a program called OrgMaker. Pixel included a program called OrganyaView which allows you to play any of the tracks of the game. The OrgView program can be found towards the bottom of this page. A translation patch for the OrganyaView program can be found in Cave Story's English patch located in the downloads page. The program, OrgMaker, which was used to create the music of Cave Story is currently being translated into English as well. The translator has given permission to host the files here. Look below for the download links.
To download the songs in .ORG format either click here for the full soundtrack or download the songs individually from the list below.
Also, if you are interested in downloading a soundtrack of the game in mp3 format, you can find a zip file of the entire soundtrack here.
For the names of the org files/resources (like requiem, kodou, vivi, mura, etc.) as opposed to the name of the song this comparison guide should help.
Track Listing (Cave Story):
Additional Tracks (Cave Story+ and Cave Story WiiWare):
Note: The track previously referred to as "Unknown" was confirmed to be a beta of Last Battle.
Internal Percussion Tracks:
This is where things get... complicated...
Cave Story hardcodes all percussion instruments (drums and whatnot) for all .org tracks played through the Cave Story engine. There are a select number of tracks that use a different percussion set to those hardcoded in Cave Story. The percussion information has been corrected in those few songs so that the .org tracks sound the same in both Cave Story and Orgmaker v1.3.4. The tracks listed below are the original .org files that sound different in Orgmaker v1.3.4 as to how they do in Cave Story.
Doukutsu BGM (OrgView)
These are programs that play the org files from Cave Story. The org files are embedded though.
