For fear of hijacking a thread, I'm starting a new one. This is a step by step of my setup, and what I've done to attempt to resolve this issue. I've done fresh installs using both the wiiu.guide AND MattKimura's Guide. Another user has a similar issue here. My Current Setup: Black 32GB WiiU Console running 5.5.1, custom DNS from TitleDB Using Brain Age, I've installed the Haxchi/CBHC exploit, installed redNAND, and autoboot to System Menu (sysNAND). Using WUPinstaller GX2 for installs. Installed one game via disc2app, then WUP installer (MarioKart8). Installed one WiiU game via eShop purchase (BOTW) Titles sourced from WiiUHelper and FunkiiU (WindwakerHD and Zelda LTTP VC) The Issues At Hand: When booting into Mocha CFW (v0.2), i cannot install ANY titles without an SD Card error (possible bad SD) I can install any and all titles in sysNAND, but certain games will not play from either sysNAND OR redNAND. When attempting to play games imported to my WiiU console, both from WiiU USB Helper and FunkiiU, I am able to play most VC titles tested, but ALL WiiU titles freeze on launch. I get three possible outcomes: Freezes on VC or Game splash screen Gets past splash screen, but freezes on a black screen Says there is an error with the USB storage device "Error 160-4205" What I've done to test: From sysNAND: Booting Mario Kart 8 works as intended. Booting Zelda BOTW works as intended. Booting ZeldaLTTP VC works with no issues. Can save game, close, etc. Booting Windwaker HD allows me to reach create save, then freezes on black screen. Subsequent boots freeze after loading screen to black. From redNAND: Booting Mario Kart 8 works as intended. Booting Zelda BOTW works as intended. Booting ZeldaLTTP VC works with no issues. Can save game, close, etc. Booting Windwaker HD allows me to reach create save, then freezes on black screen. Subsequent boots freeze after loading screen to black. Other Attempts: Using Homebrew Appstore, installed SigPatcher2sysmenu and tried to run it, then the game. No go I've tried this with a dozen different games, all the same outcome. VC titles load with no issues. WiiU games do not. Please, I really need assistance. Thanks for any guidance.
