Don't know if anyone still cares, but I have found a method of getting the game to run without graphics errors. First, you will need WolfRPG editor. Place the data folder into the editor, run the editor, and click file. Then select Create game data, Don't change options (name can be changed), and create the data. Inside that foolder (the folder where the data was placed) copy the rest of the original game data into that file as well. DO NOT overwrite, if it wants you to replace files, do not do that. Game should work now - sorry for any bad explanations.
