People are being mean to you because:
a) People gave you an answer and you admitted you didn't even bother to read the whole thing. Disrespectful.
b) This topic comes up all the time.
Now, read this whole thing:
You're talking about something like
this. This video is playing pretty lagless with no desync. The thing is, they are using a "buffer" to keep it like that, which reduces the control you have over your character and just feels meh. This is a mostly competitive smash community. So that stuff is not acceptable. This video also is missing characters like Game and Watch, Peach, and Luigi who have randomized moves which could desync the game. Also, these guys have great computer speeds, and it's unclear if they are even separated by a decent distance and how their internet speed is. We are uninterested in this because its just not like being in the same room, but if you want to play someone on some meh online service the
tutorial is in the description of that video. Knock yourself out. (you'll have to find someone to play though)
As for the rest of us, we'll wait for a quality release.
