I can chime in regarding SimCity 2000:
The DOS version from GOG does have a setup file, but it's not important for what you're doing here. This image shows the Mac version, but it's the same on all platforms:
If you wanted to run the Windows 95 version, someone made a patch that allows it to run on modern Windows. I don't remember where to find it though. You can Google around. In my experience, the DOSBox version crashes less often if I recall correctly, but I could be misremembering because I preferred the DOS version because it properly supported better soundcards.
As for SimCity Classic, there might be a similar option, or you might be able to rip out the MIDI files. I dunno, I never played SimCity Classic.
