Here's a thread I found on the vogons forum. It looks like there's precious little you can do unfortunately - but I hope it saves you a couple of hours if you don't bother using VirtualBox. There's an online version on archive.org, you could give it a try. I'd also try to find an old PC magazine that is period appropriate and check if their contemporary reviews have anything to say on the subject.
I didn't find any system requirements, but please try to setup DOSBox if it was an appropriate machine for the era you emulate if you haven't already - CPU speed, memory size, HDD, CD drive emulation, etc.
There's also a Win95 version of SimTown and even though 95 is difficult to setup it might be an alternative. Personally, I'd try VMware or VirtualBox to work with Win95.
Just my two cents. Best of luck to you in playing.
