Tried to run this game on windows 7(32, VM), but the game dosen't open and it says "error 1503"(it asks for the original disk) . Tried to run the archives in the .cue but they can even execute. It gives a error. Well, tell me if I am doing something wrong and if I you can run it give more details in how to do it please. thx.
