The main addition is the new interface.c file: It encapsulates all those APIs that interface with the JavaScript/Web world. In this "old" version of libxmp two fixes in some original files are needed to resolve complier problems (these no longer are needed in more recent versions). Howto build: You'll need Emscripten (I used the win installer on WinXP: emsdk-1.13.0-full-32bit.exe which could be found here: http://kripken.github.io/emscripten-site/docs/getting_started/downloads.html) I did not need to perform ANY additions or manual changes on the installation. The below instructions assume that the libxmp-4.2.8 project folder has been moved into the main emscripten folder (maybe not necessary) and that a command prompt has been opened within that project folder, and that the Emscripten environment vars have been set (run emsdk_env.bat). Running the makeEmscripten.bat in the libxmp-4.2.8 project folder will generate a JavaScript 'xmp' library (webXmp.js) including the above mentioned interface APIs. This generated lib is then used from some manually written JavaScript/WebAudio code (see htdocs_xmp/sample_player.js). The two files can easily be pasted into one and minified if desired. An example how the player can then be used from HTML can be found in htdocs/index.html
