Import DIVISIONINFO.TXT = root
textuisystem.txt = server_dep\silkroad\textdata
The above file has BSRO 1-2 and Diamond.
or use the file above (SRODivisionGen) to generate a multiple division file.
To make it display something other than "Yahoo Division #" on the launcher, Open textuisystem.txt under server_dep\silkroad\textdata and search for "Yahoo" then change them to whatever you like.
Hope this helps,
Note: The client we use(vSRO) is locale 22 if i remember correctly, So at the top make sure it's set to 22.
