A simple Win32 console tool that searches given file for XMIDI files inside and extracts whatever it found. It would name any found files 1.xmi, 2.xmi etc.; useful for extracting XMIDI from MIDPAK/AIL/MSS games for further playback.

Note that GTL (*.AD, *.OPL, and sometimes *.MT) files are often needed for XMI playback. You can almost always find that in your game directory. The only game I remember storing GTL files within an archive is Ultima VIII.

If you are unsure whether your game is based on MIDPAK/AIL/MSS, look for *.ADV/A32*.DLL/*.MDI/*.AD/*.OPL files. If ones are present, there's high probability that you will find XMI files too.

If you are unsure which game file(s) you should inspect for XMIDI, try searching for files which contain "XDIRINFO".
