I have a 4.1u Wii and after installing Rev 17, NSMB and Metroid Prime Trilogy stopped working in the disc channel. I had rev 14 before that. I tried recovering my wii to my nand but that didn't help either. I installed rev18 and still no luck. I tried restoring trucha and now NBA 2k10 will ask me to update to play it. Would installing 4.2 help the issue?
