Well, it's D:\win32app\pc64win\setup.exe in my case. I already ran said installer, and it ran fine with it's own included Joystick.c64 program. It's just that one ROM(at least as far as I've tested) that actually crashed the emulator, then SB2.0 drivers, then Windows(hanging the whole machine inside UniPCemu).
The last fault I saw was a stack fault, but I don't remember where it was. No faults after that one, though.
Edit: Currently installing Creatures. 1%... It's very slow, about 60 seconds for 1% progress it seems. (15% speed at 3MIPS Pentium CPU).
Edit: 17%.

Edit: Interestingly, WhatVGA, which ran until a while back(before the CPU fixes I made) now crashes when ran, immediately after the PCI scan?
