I'm redoing a PC as my Mario Bros MAME cabinet PC went "bye bye!"
As such I'm updating my Mario Bros MaLa layout. I've added sound effects to the layout (no music by default for the layout itself).
Then I've added a few Mario Bros specific tunes to play as background music. (typically I've used the Arcade Ambiance Project....which I love)
Anyway I find that MaLa wont play these tunes upon start up. The sound effects work, but the tunes wont play.
Before I thought I read something about one of the options, be it the fade in/out or something that effected this.
But I've played with the options and no definitive fix.
