A few questions regarding the Arcturus files

[JDoeBoy]

Howdy all, I have managed to set up and compile a working client/server using some very old SHO files for iRose. The code is edited some, but seems to be fairly clean and old, it still appears to use ITEM_DROP.STB.

My questions are regarding the running, and setup of the server.

The language folder

How are these files used, and is there a way to recreate them from the client files?​

Can I rename the STB files from the client to include the "_s" or similar?​

Are there any guides that will help me understand what those files are?​

The ITEM_DROP.STB

Is there an easy way to edit this file? If you know the file, you know why I ask.​

Would I be better to try and find code to replace the drop system? (any available?)​

LIST_ZONE.STB and LIST_ZONEZ.STB

Why are there two different zone files?​

This one isn't as explanatory as I would expect, and I have not seen an explanation of the fields anywhere.​

I know that probably isn't all, but any help would be greatly appreciated.
