Fallout 1 has an easier patch setup running off DOS or even DOSbox as opposed to the windows executable which, if I remember right, is a bit buggier.
Actually for FO2 it's probably better to do the Windows version and rock out with the Hi-Res patches. The game is that much prettier that way. However it's nice to not tie up the main PC with FO2 when I like to chat, program and flirt with kinky women on that.
... such a waste of horsepower. Heh.
