Hi, This is my first post and I've tried to look for an answer but could'nt find it on the forum. So, here is my question... If I take a game like Mario Kart 8, the data structure is: Game\data\Code Game\data\Content Game\data\Meta Game\system\02 Game\system\03 On the other end, if I take New Super Mario Bros. Wii U, the data structure is: Game\Code Game\Content Game\Meta Are the \system\ folders necessary ? I've tried booting Mario Kart 8 without the \system\ folders and it does work. Would it work on the Wii U also ? What is the function of the \system\ folder ? Thanks in advance for your answers !
