Well I got the legit EU demo from eShop using a code.
I now have yet another shiny icon on my homescreen. (i put it next to 3D colors or whatever its called)
I was too excited about launching this specific game.
I was in Gateway mode so I tried launching it. 3DS/Nintendo bootlogo. Black screens until forever.
Well this didn't surprise me. I went into classic mode and tried again. 3DS/Nintendo bootlogo. Black screens until forever.
I am either doing something wrong or gateway's emuNAND can't launch Smash Bros (Demo) yet.
