Diablo 1 HD Hellfire Mod | Awake

Hi all, i am new and just installed Tchernobog v0.1.2b
it mentions i missed a file "diabdat.mpq" to run

i want to play with in multiplayer mode , how to ? Thanks

put the mod into original diablo folder, that's installation
launch Tchernobog exe

I have moved "Data" folder and "Log_Srv" folder from old version diablo 1 (that installed and played 1 year ago) to this today updated patch, this approach is correct? and where i can multi-player with yours?? Thanks
