Here’s some bits of info on how you can replace the existing MP3 files in UO with your own MP3s. I think we might be making a more comprehensive version of what I’m about to write about at some point, so I’ll just hit some of the high points.
Changing which MP3 is playing
Those who have registered and play either the 2D or 3D versions of UO:LBR will sometimes hear special MP3 music playing. These MP3 files are stored within the Ultima Online\music\Digital\ directory. Also within that directory is a config.txt file. Users of UO:LBR have the option of playing their own supplied MP3s, rather than the ones that are installed with UO:LBR, in one of two possible ways.
Swapping MP3s: Open the directory mentioned above and find the song you want to replace. Save that song in another directory, in case you want to replace it back where it started. Find the new song and place it into the music\Digital directory, and re-name it to be exactly the same as the one that it is replacing, and you’re done.
For example, if the official song file is “Bucsden.mp3″ and your replacement song is “Carmina Burana.mp3″ (by Carl Orff), save “Bucsden.mp3″ in some backup folder outside the UO directory, copy “Carmina Burana.mp3″ into the “Ultima Online\music\Digital\” directory, and rename that copy of “Carmina Burana.mp3″ to “Bucsden.mp3″
Changing the config.txt file: Open the “Ultima Online\music\Digitial\” directory and look for the “config.txt” file. Save that file in another directory, in case you want to revert everything back later to “square one.”
Copy your new song into this directory, and we’ll use as an example a file named “Carmina Burana.mp3.” You should simplify the song name before proceeding, removing any spaces or special characters, so that something like “Carmina Burana.mp3″ could become “carminaburana.mp3″ or something along those lines.
Open the config.txt file in that directory and look for the line which contains the name of the song you’d like to replace. For example, you might change the line that reads “22 vesper1″ to become “22 carminaburana”–and after doing so, restart your game client for the change to take effect.
I’ll need to refer back to that config.txt file for this one (at “Ultima Online\music\Digitial\config.txt”). If you want a certain song to playback forever in a loop, open that file and look for the song listing you’d like to change. Changing “22 vesper1″ to “22 vesper1,loop” will activate the looping process for the song “vesper1.mp3.” Without that extra “,loop” comment, the song will only play through once, and then end.
Note: When you leave the associated area or stop/complete the associated activity, the song will cease. We’re looking into somehow allowing such music events to fade the music rather than allow it to stop so abruptly.
