Hi guys. I found a nice library which plays many mod-formats. It is written by nickysn, the creator of PTCPas. For now it decodes the modules in a wav sound file. I played with the source code and created small, not so precise command-line player, which plays the modules thru the openal library. You need a SVN client to download the source code.
