well, there are some crappy b-net DI + II mods, I think, but nothing serious. There's just a mod on the side wc3*************, but its a mod for diablo III.
oh, i have a question : can i extract files like sounds from diablo I and put these into my map (in the loading screen, i write i took diablo i files) ??? CAN I???
hmmm, didnt know that these symbols ("*") are also coming when i write mod forge... well, here is the site: www.wc3mod forge.com/ (you have to write mod forge together)
