Every time I try to import an mp3 file into the materialbase of rpg maker xp, when I try to play it nothing happens. Has anyone else had this problem and can someone please help me with this?
Don't use "Import". Just copy/move the mp3 file to the Audio\BGM (or appropriate) folder inside your project folder.
Also check the properties of the MP3. If the kbps (sample rate) is too high, it won't play.
