I'm not familiar with older hardware, could this play the early fallout games?
Fallout 1/2 might:

As long as the FPU and MMX instruction set can be emulated by Windows or it's drivers inside UniPCemu (it doesn't support them itself, other than trapping #UD exceptions and FPU emulation exceptions, which might be possible with the right drivers on 9x/NT 3.1). NT 4.0 and up(2000/XP and up) don't boot properly yet(NT 4 runa till it reaches the desktop for the GUI part of setup, after which it crashes so far. I'm still trying to figure that one out why that happens and what unknown CPU bug causes it).
Edit: NT4 installs and runs properly now. No 2K/XP yet though, due to unknown boot device issues.
