Hacking Gateway and homebrew launcher ?

[alucard_xs]

HI dudes,

I need to install The homebrew channel on my 2DS but I do not know how to do that.
Actually I've got a Gateway cartridge, I installed the homebrew launcher.cia, it installed great but I've got a black/red screen when I launch it within my emunand.
Do I have to launch it in sysnand ?

Thanks
