Is worst when you actually boot the HBL, you get happy and excited, then you choose the homebrew to load and then it doesn't. Now is like playing with you.It takes me roughly 3-4 retries to boot lol
Though when you're a homebrew dev, that's nothing, normal users I recommend honestly to just wait.
If only homebrew loading was more stable like other systems, even wii homebrew channel or WII U Haxchi.
