GOG Wing Commander IV DOS Fix

The good people at GOG include a download of the original DOS version of Wing Commander IV as a bonus feature when you purchase their digital release (which is based on the Windows 95 DVD release). That's great news for anyone who wants to play Wing Commander IV the same way they did back in February 1996... except that the copy on GOG is broken! Several of the MUSIC files are corrupt which results in an inevitable, game-breaking crash on loading a mission once you arrive at later CDs.

To correct the issue, we've put correct versions of the bad files online here. Simply use this archive to replace MUSIC1 through MUSIC4 in your /Wing Commander IV - DOS Version/CD1 folder and the game will work correctly going forward. If you've already experienced the crash be sure and first load a mission from CD1 in order to clear the corrupt MUSIC file from the game's cache.
