Hi! I bought xbox 360 freestyle 3 and now Ive transferred a few older 1 disc games to it by ISO2GOD, but I have no idea how to install/transfer 2 disc games? For example Ive downloaded Skyrim, Assasins Creed IV and GTA V and I have no clue what to do with them.. Could someone please explain and help me I would really appreciate it!
