Rock Band instruments don't work on replaced Wii
So, I had a Wii a while back, bought it like 2 years ago. It was working find with my Rock Band 3 drums and guitar.
I swapped it out for a replacement through Best Buy and they gave me a refurbished system, I think it's older. I did the soft mod, same as my previous Wii, but my Rock Band instruments won't work now. The dongles will detect the instrument and show the light and all, but the instrument buttons don't do anything in the game or even in the Wii menus. Also, I have to turn the Wii on with the dongles plugged in while the instrument is turned on as well. If I press the buttons on the dongle to "detect" the instrument, to sync up with it, the dongle will turn itself off and doesn't function until I restart the Wii again.
Any ideas? Is this a Wii problem, not compatible with the newer Rock Band 3 instruments, or is it a softmod issue that I need to update something?
