I'm desperately trying to figure this out. After doing it with Warcraft III following these instructions: http://antjedi.homeip.net/wordpress/?p=19 I'm looking at the preference files in Diablo 2 to try and do the same. So far, after changing the resolutions, my screen stays at res, but the game just sits in a black box. Anyone have any clues/pointers? I know there is a hack for the windows version - any way that could be ported over? I was thinking of using crossover to play diablo 2 in mac and install the windows hack that way? Cheers! I'm only playing single player, by the way.
