As far as I can tell, this is just Haxchi with a homebrew pack, custom Haxchi config and a reskinned HBL .elf right?
So there's nothing in there that people couldn't do themselves by downloading the homebrew they want and adding button mappings to them in the Haxchi config.
Still useful for those who are too lazy to configure Haxchi themselves I guess.
Although personally I prefer to boot into HBL and select the homebrew from there. I can't remember what homebrew each of the 10 different buttons launch and it's easier to just boot into HBL at that point than risking pressing the wrong button and having to press Home and wait for HBL to load again.
What interests me though is that Sig Patch -> HBL shortcut. Is that done using a modded Simple Sig Patcher? I always find it to be a hassle to boot Haxchi, wait for the system to basically reboot, then boot it again to go into WUPInstaller.
