@FIX94 I don't know if this is a bug with CBHC, a certain WiiU game or Dimok's Homebrew Channel 2.1.
I just installed CBHC 1.2 on my PAL console, successfully tonight and enabled the auto-boot to system menu. Everything seems to work fine for my USB installed titles inc, DLC and VC thanks to the signature patching.
However, I have found an issue with one particular title so far (Hyrule Warriors with the latest update patch and DLC) Basically, what happens is when I load the HBC and exit back to the main menu, selecting this title causes it to crash requiring a hard reset 100% of the time.
But, if I don't load the HBC at all after CBHC has booted to the main menu and I select same game again, it works fine, yet if I load the HBC and exit, the crash will happen again.
So far, I have tested Mario Kart 8, Smash Bros and Xenoblade, which all have their latest updates and DLC applied and those are fine after using the HBC after boot, so I find it weird that Hyrule Warriors crashes.
