I have a USA region Wii U. I have Haxchi installed over Brain Training. I've downloaded most games through Wii USB Helper. Haxchi is set to load sysmenu by default. I run Haxchi and then install games through either WUP Installer GX2 or wupinstaller y mod 1.3. I've been installing games to a USB drive attached by a Y cable to the back USB ports. Installation has for the most part not been a problem, although a couple larger games did hang while installing (didn't hang the system though as I could still press the home button). Anyway, after successfully installing a mix of VC and WII U games, I've been having trouble launching many of them. Some work just fine, but others give a mix of three issues. 1. Freezes on VC or Game splash screen 2. Gets past splash screen, but freezes on a black screen 3. Says there is an error with the USB storage device "Error 160-4205" I notice the games that freeze on a black screen do make it far enough to create save data. After problems with a game I have tried re-downloading, using different SD cards for installation, and installing to a USB stick. I managed to get two VC games that didn't work to work, but for most part the games that don't work, I am unable to fix. Not a single Wii U game has worked. Some examples include: Mario Maker freezes on the splash screen, Star Fox Guard freezes on a black screen, Axiom Verge freezes with error 160-4205, Fire Emblem freezes on the splash screen. Any idea what could be causing this? Thanks.
