Here's the KOTOR Remix I've been working on, on and off, for the better part of a year. It's a direct link:

(Copy/paste the remixed version of the character you want from the appropriate "group" folder to the Override. Listed at the end of the post are the different alternate characters you can choose from. If anyone has a more elegant system for integrating these PCs than dumping them into the override, please let me know.)

I've got kind of a problem with it, though. For some reason, none of the remixed Carths seem to want to initiate the proper dialogues after the PC wakes up in the Taris apartment. Any chance someone more knowledgeable than me could have a peek and tell me what's wrong?

This is good news. I've been waiting for an update for KotOR Remix. I have some experience with editing dialogs so think I might be able to help you with the bug. Downloading now...

Well. I played through the Endar Spire and early Taris with the mod installed and had no problems with Carth's dialog or vision of Bastila fighting on the bridge of Revan's flagship. Everything triggered correctly. The issue you had is propably caused by some other mod instead of the remixed p_carth.utc if you have any installed.

I found out from dialog file tar02_carth022.dlg and its attached scripts that mods that start the PC as a Jedi will probably mess with the starting conditionals of the dialog (k_pend_bedmed.nss, k_pend_bedsml.nss, k_pend_bedtal.nss and k_pend_bedtiny.nss).

You can download the "KotOR1 Fixed Cutscene Files" to solve the problem with the character being "pure" jedi or not having a normal gender (if that's the scenario you're having). http://www.starwarsknights.com/tools.php)

There isn't actually anything in there that's supposed to make the character be a Jedi instead of one of the standard classes. Is everyone else able to properly recruit Carth when using one of his remixed versions? That's the main problem I had.
