I've got a Wii, currently running 4.1E, shop channel works etc. Think it's got ios 60 patched, HBC and bootmii, but other than that not a lot else. I don't use a USB hard drive or gamma/disk loading etc. Just got hold of Rock Band Beatles. Now, will i need to change anything to be able to play it just with a microphone. I think i'm on cIOS v10 if that makes a difference? Just i'm sure I read there were problems with USB instruments and cIOS?
