Of course it's one thing to know that something's possible and another thing to pull it off. I always suspected that true CD-free in-game music would be possible by intercepting the game's DirectX audio disc calls and playing music files from the hard drive instead. The only solution before now has been to mount an audio disc image to your hard drive, but this is a complicated and annoying process that requires you to install a special program/driver, mount the disc and reorder your drive letters every time you start the game, etc. This means that if you play with the NoCD patch you can't hear the music in-game. Like many games from the 90s, TA uses a disc-based soundtrack, meaning the game will play music off of the CD and nothing else.
