I am providing an .iso and an .mdx file of the original CD. The .iso is copied using WinCDEmu; towards the end of this process it said there were some bad sectors, but the .iso still runs in DOSBox. The .mdx is copied using Daemon Tools Lite; there was no notification of bad sectors, but I believe it has to be converted to an .iso to work in DOSbox.
Music files are located in the 'AUDMULT' folder as .aif files, playable using VLC Media Player.
I have not tested if all sound/music files work in DOSBox under Windows 98 emulation, but it does install (if providing a shortcut to the Start Menu counts) and the initial startup plays the intro cutscene, music, and character voices.
