Once you have downloaded a folder named something like O2Mania_Full_Fixed_Pack.rar, follow these steps exactly to avoid the dreaded "White Screen of Death."

Even with a full fixed pack, you might encounter issues. Here is the pro fix for the three remaining ghosts:
Problem: "First song plays fine, second song has no sound."
