In order to implement proper support for the AMIGA version of Monkey Island, the TFMX interpreter developed obviously needs to function correctly with Monkey Island’s data files. In turns out, after some poking around, that the demo version of Monkey Island has the complete audio track in it. You can obtain a copy of the demo here. The demo is in .lzh format, a disc image format for the AMIGA. You can actually extract the files from the demo using WinRAR or other command line utilities if you are on Linux. The audio files are music.dat and sample.dat contained in the Rooms sub-directory. Comparing these files to the files from the actual full AMIGA version of Monkey Island shows they are identical. The files from the full version have the same structure, headers, and size.

If have a copy of the full version you can check them and compare for yourself.
