This offers various advantages over the existing Vita ports of Doom including most of the Chocolate Doom features, dual stick control, OPL3 and .ogg music support.
Here's how to use .ogg files for better quality Roland SC-55 music.

This offers various advantages over the existing Vita ports of Doom including most of the Chocolate Doom features, dual stick control, OPL3 and .ogg music support.
Here's how to use .ogg files for better quality Roland SC-55 music.
I have created some .cfg files that allow you to use .ogg music. Or more accurately, I have edited the existing .cfg files for the .flac files to use the .ogg files compatible with the Vita port. I literally opened the .cfg files and changed all the .flac extensions to .ogg. Chocolate Doom does not seem to care if the SHA1 hashes are correct.
Create /data/chocolate/music/. Go to Roland SC-55 Music Packs and download the .ogg packs for Doom, Doom 2 and Final Doom. You can also get the Hexen music pack here. These archives will contain a folder called MUSIC. Rename this folder to either doom1-music, doom2-music, tnt-music, hexen-music, heretic-music or strife-music depending on the game and copy that folder to /data/chocolate/music/. Also copy the .cfg files from the attached archive into /data/chocolate/music.
You should end up with the following structure:
music/
----[game_name]-music/
--------<OGGs here>
----[game_name]-music.cfg
Now in the Chocolate Doom settigs, switch the sound from OPL3 to Digital and enjoy glorious Roland SC-55 music.
