I'm getting ready to start a playthrough too.
I've downloaded a selection of the confirmed compatible mods from this list:
http://deadlystream.com/forum/topic/3348-list-of-k1r-compatible-mods/
But I've also downloaded a few others that I thought sounded good, and I'd like to know how to determine if they are compatible or not.
Here's the list of mods I'm wondering about:
http://deadlystream.com/forum/files/file/375-korriban-academy-workbench/
http://deadlystream.com/forum/files/file/351-juhani-catlike-head-mod/
http://deadlystream.com/forum/files/file/362-kotor-dialogue-fixes/
That last one, dialogue fixes, is the one I'm most concerned about, since I think K1R also edits dialogue...
Edit: Watching the process as I install K1R, I see that modifying dialog.tlk is the first thing it does.
Looking into the files of the dialogue fix mod, I see that it just provides a modified dialog.tlk file, no TSL patcher installer.
The readme does seem to contain a list of all the fixes it makes though, so maybe I'll try searching the dialog.tlk of K1R and see if this mod is even needed...
Edit Again: Got KOTOR Tool and opened dialog.tlk to have a look. Can't find a way of searching for a particular text string, so I can't easily check for the changes that mod makes.
Edit once more: Found the Export to XML option, then opening the XML file in a text editor I could search.
Found the line containing "Congradulations", so I guess these changes haven't been included in K1R.
Is there a way to use TSLPatcher to make the changes, or should I manually search and edit the XML file?
MOAR Edit: After installing K1R and all the confirmed compatible mods I wanted, I've now tried installing the Korriban Academy Workbench mod, which requires me to copy its four files into the Override folder.
None of them were already there, so I guess it's compatible...
Same deal with Juhani catlike head mod. No conflicts with existing files in the Override folder, and no warnings when installing the item section with TSLPatcher.
Edit some more: After spending a couple of days thinking about it, I've come to the conclusion that the dialogue fixes mod can probably be used along with everything else as long as I install it first before installing anything else.
That way it will replace the original dialog.tlk file with its fixed version, and then K1R and the other mods will all make their own modifications to that file as I install them.
I'll try it like that and report back.
