The modified GUI files will not show up correctly at 1360x768, they are resolution specific, so that is expected behavior.
1530x864 should appear in the list in the game's option if the game is patched with UniWS correctly. I'm the creator of the modified GUI files and I used that resolution myself because I used to have a 1360x768 TV at one point (upgraded to a 1080p display a while back).
If you believe you've patched the game to 1530x864 correctly and the option is still not appearing in the menu for some reason, you should still be able to set the resolution through he ini file. In the main game directory there should be a kotor.ini or something similar (I forget the exact filename). Go ahead and open that up after patching the game and you should see height & width settings. Change them appropriately.
If the game doesn't start correctly at that point either the game was not patched correctly, or the custom resolution (on the video card side) is not working correctly.
Ok, thanks for the reply and it has half worked. I modified the .ini so the game now runs at the correct resolution but the screen is out of sync.
What I mean is that when I go to click on a menu button for example, the mouse isn't aligned with the screen, so I'll have to go lower then the menu button to highlight it.
Also, the convo options appear but half the HUD (except the health bar and portrait which is in exactly the right place) has gone off screen. Any ideas now?
Sorry to be a pain in the arse.
