I bought a third-party Rock Band 2 drums (http://www.mercadolibre.com.ar/jm/im...5_7246.jpg&v=O), I followed Rock Band 2 guide to make the instruments work. But no luck, it ain't working.
I've tried EVERYTHING, any suggested CIOS, patches, whatever. It doesn't work.
My wii is 4.1U, no chip for backups, it's practically "virgin" except for Homebrew Channel stuff.
Can someone close this topic? Installed cIOSCORP V3.6 and it worked ^^
