Indeed. This is where first mentions of ZP and POD are as well. Where I found out bout ZP before it was even talked about, along with all the other stuff you pointed.
I do know that the version of hotkeys we have today was not the original, infact I believe there were multiple iterations of it. This seems to be a static-but-updateable list of strings* the game uses. Such as hotkeys. I'm assuming the extra emotes were never actually added to the game movement wise, but that's just speculation as to why we never saw them.
The Audio folders hold the games music. The 2 fronts and 1 prefronts games seem to held music I have never heard, but they all sounded broke (the ones I've never heard, or think I've never heard). However, I had to use a converting program to convert them to MP3, so it make have just been the programs fault. However, it did convert a number of them completely fine, so I think they may have been saving those audios as they only had 3mb of update space, or that they couldn't get the audios to work, and thus never used them. But then that makes me wonder why they would've put it on Fronts in the first place, if it didn't work on prefronts.
If you look around some more, you'll see a file called Tunaria that is not much bigger than a gig. You should also find Odus and a file for the "great unknown".
I found a lot more interesting stuff too, but I can't quite recall them right now.
The EULA you agree to is a text file on the disk.
*A string is a type of programming variable that holds 'characters' ('boob' 'job33' 'dudet:.<' are strings, and string can also be only numbers (though variable types exist that are specifically for numbers))
p.s.
You know how %2 %3 %4 translate into <Your level> <Your class> <Your Target>? I know I saw some strings in prolly that file that have a different %#, like %1.
Forget to mention: Also, I do believe you can find the GM commands there too. Names anyway. No access to them if your account isn't flagged.
