I updated to Omega 2.2, dumped my mario kart 7 cartridge, and renamed it to 3dz. When I go to play online it gives me an error that I need to update the software via eshop. How do I fix this? Can eshop be used to update the software without updating my system? If so, whats the process of updating mario kart 7's software via eshop? Thank you.
