this is very interesting. I have played this game also for years and was one of my favs.
I would like to help you with everything I can.
I also have this client: Solstice-01_36_0002.exe
Unfortunately the torrent does not start downloading, so I cant check the requests and responses at the moment to see if I can make a server script.
The version 01_36 does not start.
Edit: I found the 01_31 on gamefront.
After I select the character, the game goes all black. Do I miss something?
Edit 2: Xen Online works best I guess. I would like to check solstice reborn. because it was the most completed one.
Im not good with hex and bytes.. sooo this may take a while
You did an awesome job there!
