Heh...I’m still playing Nethack...so I probably shouldn’t be on the ask list....
Seems like there should be a way of running them in compatibility mode on Vista. Does it let you install them? If you right-click on the game icon and go to properties, is there a compatibility tab with possible adjustments?
Not that I know enough about games to really know if that’d make a difference...maybe someone else will speak up.
Still my favorite time-waster, next to FR. I'm pleased to have the latest versions on both the PC and the Palm.
