For Windows XP/Vista users: If the game doesn't run, rename ddraw_winXP-Vista.dll and libcurl_winXP-Vista.dll to ddraw.dll/libcurl.dll and try running the game again. The Windows XP/Vista compatibility dll's were tested/provided by Darkstar!
The game now uses a compatibility layer to run fullscreen. It should automatically stretch to widescreen. If you don't like the look/feel of the DirectX rendering, rename ddraw_oldschol.dll to ddraw.dll. This will make the client use the oldschool direct drawing method again. If you use the old-school version of direct draw, you wll need to set 16 bit color compatibility mode by right-clicking moac.exe.
The latest version of the client is powered by Dege's awesome direct draw compatibility layer! It converts old rendering methods to modern versions of DirectX! If you have no idea what this means, just take if from me: it's awesome..
