Hi, a friend of mine gave me his WiiU that he hasn't been using since forever. There are a couple of things i am kind of clueless about, and i tried to gather as much info as possible in this and other forums, but now i am kind of stuck. The only real staring point i had was this "CBHC" notification during boot, so i thought i might put my question in here. If that's a bad idea, please advise me where to do it instead, thank you.
so here it is: There is a pirated game on the console, which i can play without problems. There is also an app called homebrewchannel which does nothing really, but that's most likely because there is no SD card in the system. He also gave me like 7-8 original games on discs with the console. However, i can start only one of these discs and play. All the other ones are requesting to update, which fails because i didn't connect the system to the internet (yet). So, what exactly is happening here? Do i need to boot into another CFW to play these games? Can i just update these games via the official way?
Edit: The fw version is stated with 99.99.99, but this is also just "cosmetic", correct? Is there a way to find out the actual fw version?
