Damn, I got the game to load a modified HFS, but it crashed after I selected a character.
So I guess I'm not doing it properly.
Edit: Got it working.

It's DT's Colhen mod. I made it work on the TW 2015112501_485114 client.
All I did was paste the end of our HFS onto the end of the Colhen mod HFS, to get the same file size.
I tried doing that a few days ago with my old HFS repacker, but it didn't work.
I guess the DT people are using an updated repacker?
I can't even unpack their Colhen HFS with our HFS tools, it just gives me a 1kb file.
But I was able to unpack their voice mod. Hmm.
Edit2: Disregard what I said about it being the database file. I got these HFS files mixed up.
So far all I've been able to do is get DT's modded HFS to work on our client.
I haven't been able to repack edited HFS using the tools I have.
There are some differences in the file data if I try to repack DT's voice HFS, so they must be using an updated repacker.
