RealFlight G2 from great planes will work on Windows 2000. You can look at the system requirements here. I think that you have to use the interface cord that comes with G2 [it plugs in to your parallel port]. Just get the version with the interface cord [if that is what you want] or you can get the dummy transmitter that plugs in to your MIDI/Game port

Good Luck,
