You should use the installer it came with, which is TSLPatcher.
However, after taking a second look I noticed I was testing a previous version which I still had on my local and not the latest release. I'll see what's wrong with the latest version.

No, my release is actually based on that older Yavin mod.
This project started as a side effect of my experiments with KOTOR resources. First I took Sleheyron 2.1 and translated it into my native language. I wanted to see how more modern modders approached KOTOR modding, and it was a very enjoyable experience. That mod felt cleaner, better structured, and easier to read and work with.
After that experiment, I decided to go in the opposite direction and try absolute legacy content, so I picked the old Yavin mod — the one with Exar Kun and Trask at the end.
All I can say is that I really liked it. I was impressed by how elegantly modders of that time worked around the engine’s limitations and solved difficult problems with the tools they had. Unfortunately, those elegant solutions also made the mod very conflict-heavy, so I had to spend a lot of time making it stable and playable again.
At the end of all that work, I was met with a very disappointing Trask fight. By that point, after gaining experience with the game’s resources, I decided to finally add something I had wanted to see in KOTOR since childhood: Revan’s Mask. I implemented it as a helmet, without using a full-body player model replacement.
So that is really what this release is:
a restoration of the old Yavin mod’s playability, plus a new final battle, plus Revan’s Mask as the reward.
Thank you !!!
1. In short I don't have the skills. I only know how to work on existing textures.
2. Yes I know. I fixed it on one iteration but I didn't like how it looked, weierdly looks better with the clipping (in my opinion, don't know why, something about the body proportions). Now I don't have time to work on it and also I'm kind of burned out with modding. When I will have some time I will give another shot on fixing it.
