+Rep to you, Spooce-aholic for reminding me of my childhood - Theme Hospital was an awesome game that I still like to go back to occasionally.
Also it's funny that in terms of Midi, the Roland MT-32 is pretty much unbeaten in terms of quality as a Midi card - Even better than today's cards. Good luck fitting that monster in your case, though.
I'm glad game music is MP3s now though and Midi is a long-since phased-out thing, even if I do love nostalgia... I used to have a SoundBlaster AWE 64 in my old rig back in the day and wish that current on-board soundcards had midi that sounded as good as that whenever I decide to play ancient DOS classics.
