Works fine in DevilutionX, DiabloWeb is no longer maintained so you might want to use it instead.

DiabloWeb is no longer maintained

Aha! Well, this is disappointing, given that it has just received coverage from no other than Ars Technica itself.

Pretty sure that's not the first time, and belive me I'm already well aware that it has made another round in the media. The article is also wrong, Diabloweb doesn't support hellfire, I'm guessing they got it somewhat confused with DevilutionX.

The developer that made the port chose to do so outside of the community maintained DevilutionX and didn't want to maintain it much past getting it working. I'm just giving it a bit of life support until DevilutionX has the bits in place to run in the browser as well (pretty close at this point but no one is actively working on that part).
