Hey guys, I was planning on playing a few stuff I missed in the Wii U and am trying to cacth up, so I have a few questions. a) I have Haxchi and would like to play online. Is it safe to update to 5.5.2 or will it break something? b) I read here about Haxchi V2, it's been a while, not sure how long, so not sure if I have V2 or not. What's the difference / how do I know wich version I have? c) If I have V1, should I update? Thank you guys in advance.
