I am using JB2, and I want to play AC Brotherhood, but all I get is a black screen, I downloaded and installed the package file, and I tried to put dir ASSASSIN_ISO in the usr folder, but says folder already exists?? I am doing this pc my PC, do I need any other software to do this?
You delete the folder and try to create it again, then install the pkg again and see if it works. If not you may need to delete and re-rip the game and start over. Also make sure that you delete any Game Data for it before launching the game.
