I'm using my friend's Wii to try out some games, but when the game loads and is on Wii menu, it says that a system update is required to play. He doesn't want to risk updating, thinking it might screw up his wii. Anyways, he nor I have any idea what chip his Wii is modded with. Any ideas? His other burned games work, but the ones I tried aren't working, gives the update screen.
