Well I have found where is the IOS 223, it is not in the setting of USB loader(in usb loader menu) but in the settings of the game before launch. So I can choose IOS 249, 222, 223.
But is is not working (used guitar hero world tour). So, do I have to put IOS 222 or IOS 249 in the usb loader setting and then put IOS 222 or IOS 223 in the game settings?
I AM SO LOST...can anyone help?...
