Alright, lemme be clearer then. I'll be linking the mods I mention in case you want to see what they are.
1) K1R (KotOR 1 Restoration) is the oldest big mod. Its goal is to restore content. It hasn't been updated since 2015 because the team moved on and the work was basically done anyway.
2) K1CP (KotOR 1 Community Patch) is more recent. Still being worked on. Its main goal is to fix bugs and other issues of the vanilla game, and thus not restoring content. The issue is K1R isn't compatible with K1CP.
3) Thus, someone decided to make RC-K1CP (Restored Content for K1CP) in order to replace K1R. So it's very recent, been updated in July.
4) BUT it does not restore the Pazaak Tournament. So I made it myself in order to be able to play (a fixed and improved version of) the Pazaak Tournament WITH K1CP on your game installation (although you can always play without K1CP, but it's kind of a waste).
To answer your question, yes, the best installation order is Sleheyron then my mod. In general, just start with the biggest mods (K1CP, RC-K1CP, retextures) then go the more medium mods (Pazaak Tournament, Sleheyron, BOSSR, etc.) then to the smaller ones.
If you met Bogga and he recognized you then it works. Thanks for testing. And no problem, people often misunderstand what's written, but it's also my fault for putting too much stuff in the description. It is indeed quite massive (but tbf, the mod itself isn't small either). And yes, if you have anything else to say/report, feel free.
