Pandemonium Event Single Player

[Charlemagne]

I have been researching how to do the Uber quests in single player and it seems that Plugy can do this, but everyone says that the Uber AI is wrong and they don't spawn minions etc. Surely someone has made an improvement by now that simulates the AI on the realm servers? If not, what tools would I need to use to create a plugin for Plugy or D2 in general that would allow me to alter the AI of the Uber monsters and the battle in general, so that I can experience the Uber quest in single player mode?

Thank you.
