Sorry, I'm not trying to be offensive at all. I appreciate your efforts. Its just that from my point of view, for the N64, there are already servers in place for people to play online. And for GC, connection to each other is a click away.
It is my opinion that both hamachi and port forwarding are not needed for netplay. As for emulator that is up to user preference. I only posted smash guides because they have a system where all users follow and finding a match is instant. If things broke down and you needed help the smash ladder has a FAQ for helping with connectivity and emulator issues. If everyone in the Marioparty community followed the same guidelines, finding a match and actually playing through it would be a simple task.
