First I want to say thank you for the getting my old friend Duke3D up and running again. I followed all the steps and it worked great. I haven't played this for years since it didn't work in XP and it was a blast ripping through the first couple of levels. Thank you again

Back in the day I built several levels for Duke3D and I can't seem to get them to run. I tried running them from the command prompt and as soon as it hits the sound ini it gets an error and shuts down.
The game runs great when I double click the new icon so what do I need to do to get a user.map to run.
Thanks,
Bob
