First I used Haxchi 2.0 alone and it worked fine. (I don't need cold boot.)
Then I saw Homebrew Launcher Channel 2.1 and realized, that I have to start a sign_patcher before.
For starting that, I needed Homebrew Launcher. So that was not really helpful.
Then I saw Haxchi Direct from Kohmei which would do exactly what I wanted.
So I've installed Haxchi Direct and Homebrew Launcher Channel 2.1 and it worked fine. Had no problems.
If I wanted to start Loadiine, I started Haxchi Direct, then the Homebrew Launcher Channel and from there I started Loadiine.
When I was quitting Loadiine, it went back to the Homebrew Launcher. Using the Home button, I then closed the Homebrew Launcher Channel and was back to the WiiU menu.
There I could start the Homebrew Launcher Channel again and it worked again. (As expected
)
Someone wrote Haxchi Direct would be now redundant, so I installed Haxchi 2.4 and setup the configuration button "y" to start Loadiine. So I started Haxchi 2.4, pressed "y" and got into Loadiine.
After pressing the Home button I got back to the Homebrew Launcher 1.4 which had to be on SD card now. (When it was missing the first time, I got error -5.)
After pressing the Home button again, the Homebrew Launcher exited to Mii Maker. Quitting that got me back to the WiiU menu.
Everything seemed to be fine. But then I started the Homebrew Launcher Channel and got error "199-9999". So I had to turn off the WiiU. (Reproducable.)
When I start Haxchi 2.4 with setting default=sysmenu and don't press a button I can start the Homebrew Launcher Channel, Loadiine and can use Homebrew Launcher Channel again.
It seems no patching was done, when starting Haxchi 2.4 with a button pressed, I think. (But I could be wrong )
So when I must not press a button, I could use Haxchi Direct again. But maybe it's only a bug and can be fixed.
What I really need/want, in any case, is a Loadiine Channel or a forwarder channel to Loadiine. That would be perfect.
All the best,
Calahan
