Hey, I'm new to the realm of software modification. Go easy on me.
Still having problems, the showdown on Dantooine makes the game crash every time I have movies enabled... then crashed when I tried to change the graphics setting in game...
I'll try another go at it and see what happens.
Edit: Did the lag fix, caused problems, so I undid it and haven't had any problems yet... odd.
Nope, still having problems... on Onderon and I can't even walk out the front hatch.
Edit 2: HA! Okay, I feel like an idiot now. Here's what happened:
The Vista fix regarding changing the compatability for the game by changing a setting inside the game file in programs: does NOT work for W7, it changes it right back.
Instead, when you have the shortcut on your desktop, right click it, go to properties, change it to W-XP-SP2, and Run as Administrator. USE THE SHORTCUT to open the game! Here's how you know this is actually working: when you first run EITHER KOTOR or TSL and click GAME, they scan your machine and ask you to configure it. This will not happen otherwise.
Problems solved. In fact, so well that I can run it with even better graphics than those I had while I was actually USING XP-SP2.
I might suggest using that information in a sticky about Windows 7. Could prove useful for other poor souls.
