1024x768 will be added eventually, but the problem with D2MultiRes is that it IS a cheat. You're able to see monsters before their AI activates and kill them before they're able to do anything, hence why anything higher than 1024x768 won't be supported. And D2MultiRes (not to mention how buggy it is) is a small price to pay for the much larger things that are going to be added to the mod. It's an older game. There are some things you simply have to deal with.
