Some of my mates setup and offline version which is allowed and you can see it in YT.
Still many ppl not touching the aspects of online-clients and more.
We are still working to do many other changes before anyone goes online.
Before an D2R client should get online, many other work need to be done.
And also we would like if blizzard provides us a clearance for it.
We dont need actually modding support from them more a clearance is required.
About in modding, check youtube there is a lot information provided, maybe you find the way…
