Music
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 the full soundtrack of the game in mp3 format, you can find a zip file of the entire soundtrack in here. You can also download the full soundtrack in .ogg, .xm, .ptcop, and .flac formats.
There are also two versions of the .xm soundtrack. There is a version compatible with most trackers, of which individual downloads can be found below, or there is the original conversion from org to xm, which may have compatibility issues with some trackers such as Fastracker 2 and is kept for posterity. For the most part you will only need the former unless you have a specific technical application for the latter.
Downloads exported using beta instruments (the instruments from Orgview 5 and Orgmaker 1.3.3) are available in .mp3, .ogg, and .flac formats. Individual downloads are marked with the β symbol.
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.
Note on Percussion: 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. Songs marked "Cave Story Percussion" are the songs as they sound in Cave Story, and songs marked "Internal Percussion" sound the way they do outside of Cave Story.
Track Listing (Cave Story):
Additional Tracks (Cave Story+ and Cave Story WiiWare):
Unreleased Tracks:
Note 1: The track previously referred to as "Unknown" was confirmed to be a beta of Last Battle.
Note 2: The track previously referred to as "Snoopy Cake" is actually called "Untitled" (with an internal name of ROCKORG), there is no evidence that the song was ever named "Snoopy Cake". Sorry for the confusion.
