Wow, the day has arrived, haha!
I have a 5.5.0 WiiU, I know Loadiine is for 5.3.2, but I see that it will work on 5.4.0 too. Can anyone tell if the exploit will be ported to 5.5.0 soon? I read that it will occur only if Nintendo patches that exploit, or if someone makes a way to load an emuNAND, or if a new exploit is discovered, but from time to time I read that making Loadiine work on 5.5.0 it's possible, but not for now, because the exploit is not public yet. I hope it will work soon on the latest firmware!
At least, a friend of mine has a WiiU that he never connected it to the Internet, and he only has Smash Bros. I have Splatoon, so I can update his WiiU to 5.3.2, and maybe we can exchange our consoles (he's not interested on this, luckily, so he won't have any problem), but I don't want to lose my Smash Bros and Mario Kart 8 DLC purchases, so I'm waiting for a 5.5.0 version of Loadiine.
