Neverwinter Nights (1991), The Shadow of Yserbius, Wizardry Online, any and all files

I'm looking for any and all files, source code, and documentation for any of these three games, I'm hoping to help bring them back up if at all possible, or at least help others who have tried to bring them back up. I have never looked into anything like this before so even some suggestions as to where to look would be much appreciated.

ForgottenWorld (NWN private server) site: ForgottenWorld Online Game

The Shadow of Yserbius:

http://yserbius.org/forum.php This might be the only relevant link for this game, to a forum for players
https://sites.google.com/site/innrevival/home This is the only link I can find for the private server, it's to a locked google site.

Wizardry Online:

https://youtu.be/typt2qBEgWE this is the sad one, hasn't been brought back at all, this would be the biggest achievement if at all possible, there are people that want to host it it might just be a matter of getting them the right files.

Much thanks in advance.
