The downside is the community's documentation is scattered trash compared to any other technical part of the internet.
It took me almost 10 years to finally enjoy Ocarina of Time that I have a legit VC copy of. I want to load up a majoras mask wad and all the forum posts just read like lists of codewords i'm not cool enough to know. I set this up almost a year ago, I don't remember what ios versions I installed. I'm gonna have to reboot this thing like 10 times before I figure it out.
Edit: Hacked my 3ds for advance wars, holy shit themes have sound.
I never planed on getting a Wii U but i'll keep an eye out for a cheap unit. Not sure how worth it it'd be if I already have my wii set up nice.
There are only a handful of Wii U exclusives that make it worth it if you already have a Wii. I did get mine for $60 though, which ain't bad.
