(re: Need help with GK I on Win 2000!!!)
Unfortunately, this game is a pain on XP and I would imagine it is the same on 2k. A few have had some success with DOSBox. You can search VOGONS for GK1 for help on this, but, your computer is really too slow for DOSBox. There is someone (Endroz) that is developing patches for the GK bugs, but you will have to wait. His site can be found here:
In the mean time, you could always get a copy of Windows 98 and do a dual boot on your computer with both 98 and 2k and play the game in 98.
