UPDATE: The new background .tgas didn't import to override. I keep trying, but they aren't working. The new the .txis and cards work just fine, as well as the 'rotate' button animation, but there's no working backgrounds beside original metal texture zoomed in and scrolling like a trippy trainwreck.
I'm running into an issue where, once I'm done choosing cards, the pazaak board is cycling between corners of the blown up background images. I think I've installed correctly, and I've reinstalled once already, but I'll try again.
To reiterate:
Download mod
Manually move 3 files
Extract using XnViewer into override
Start KotOR 2
Play pazaak
Choose side deck, hit next
THE ACTUAL GAME BOARD goes berserk, cycling the background with blown up images of metal textures. The cards are fine.
