Yunnlith: Have you guys tried to play with the compatibility options a bit ? I know I had an issue with crashes, so I changed that and it pretty much fixed it. (only had crashes issues with more modern Windows versions, not back then ; own the box version)
Mostly this. I also had to change both the game resolution and my desktop resolution (stupid as this sounds, it always crashed when I launched it from my monitor's native resolution), but it mostly works. Both KOTORs crash during gameplay for me, though, so when you do get it running to your satisfaction, try to get in the habit of saving right before you go anywhere that will trigger a loading screen. CTD isn't an intolerable bug for me, so I don't mind, but I do crash probably every fifth** time I change areas (including starting and ending cutscenes). Thankfully, the way KOTOR was designed, that's not too terribly often.
**it would have been much less, but the cantina on Onderon hates me and crashes more than half the time, greatly increasing the overall average. Most of the other planets only crashed once or twice the whole time I was there.
zevri: There might be, but most I know of off hand are ones for Kotor 2, including a restoration patch which adds removed content and whatnot.
Yeah, The Sith Lords Restored Content Mod (TSLRCM) is pretty much a must for playing KOTOR 2, now that's it's pretty much complete.
