Thanks for the reply, Hobbes. Here's what's happened since I took your advice...

Got WinUAE to run it, but it's _sllllloooooowwwwww_. So I'd really like to try and take one more wild stab at getting Fellow to run it.

When I tried what you said to do with Fellow, it still crashed, which lead me to wonder if it was a VESA problem, so I got Scitech Display Doctor. The good news is it's not crashing anymore. The bad news is now it's just simply freezing up when it tries to read Disk 1.

Any other suggestions?
