If you’ve ever played old games with CD audio soundtracks, you’ve probably noticed that the music in these games doesn’t loop correctly. Exactly why this happens is unclear, but it seems to be due to some changes Microsoft made to the The Media Control Interface (MCI) components in Windows Vista and later. To help with this problem, a clever Japanese author came up with the _inmm.dll software suite. This useful program can patch hundreds of old games that use CD audio and fix the music looping and playback problems. If you have an old game and the CD audio is not working correctly, follow our tutorial here and give _inmm.dll a go.
One thing I had to do extra was to copy the _inmm.dll file into the game folder as well, otherwise it wouldn’t work.
That shouldn’t be necessary if _inmm.dll is installed properly, certainly we’ve never needed to do that.
Ah yes, I used the zip version rather than the installer version, so it wasn’t “installed properly” :-)
