Forums - Nintendo Discussion - Major bug in Mario Kart Wii

MKWii and MK DS both use predictive measures to estimate what your enemies are 'probably' doing at any given time to decrease the amount of bandwidth necessary to play. It's a fairly common practice in online games.

All that happened is that the prediction was a bit off..

 It's called dead reckoning.

it probably has a lot to do with the state of the UK's broadband (asuming these problems are in the UK). My connection is technically fast enough to play online but it drops so much that it causes problems similar to this.



Seconded. The Uk's broadband is crap. That why there'll be no digital downloading (mainstream) till we have broadfband at much higher speed at same cost. My broadband is screwy for online too.

Could this be the bug your talking about? It looks pretty serious.

This is not me trying to deny I suck at Mario Kart (cause I do), but there's a major bug which annoys the hell out of me.

It doesn't happen all the time, but it happens in about 30% of the races, that when I finish (for example) second, the results say I finished 3th or 4th (or even as bad as 12th one time).

Usually this happens when somebody is close behind you, but it just happened to me in a match with Larry Lion (don't know what your name here is) that I finished second, with the third and fourth racers miles behind me. The results said I finished 4th however, which is utterly impossible. Of course, sometimes it happens in my advantage as well, but those instances are less annoying.

Is anyone experiencing this problem besides me, or do I have a jumpy network or something (all other online games work perfect, so I doubt it's the latter).


Larry Lion is TWRoO

Not had quite the same problem but races/battles have suddenly ended for no apparant reason.

EDIT: Just like that video above!! 

I think there are a few problems still being sorted out by Nintendo what with impossible lap times etc. Generally I have a good online experience, I expect problems will remain when the US joins in the fun!!

This is the best explanation so far. Makes sense.

@tmbh

I think races are automatically aborted after a certain amount of time has passed once the first player has finished the race. I estimate it to be about 30 seconds.

NO

Ive been in the lead on the 2nd lap of a race then all of a sudden the game just ends!

Has happened about 5 times to me on diferent courses.

Its possible that people have dropped out/been disconnected, but when I continue to the next race most people from the previous race are still there!

I would guess someone (maybe you actually) disconnected.

On topic, that's not actually the best explanation Rol.  It doesn't "predict" anything, what it does is send input data instead of all data.  This is what Brawl does too, but it doesn't experience this issue.

What's actually causing the issue is simple lag.  The people in front of you probably had a laggy connection and you weren't getting their input data in real time, so you couldn't see where exactly they really were.  The server could though...

Anyway, it shouldn't happen often.  Only when playing laggy people with bad connections, but yeah.  MKDS did the same thing for the same reason.   



You'd think the UK would be near Japan levels of broadband considering the country's size...

Bet with disolitude: Left4Dead will have a higher Metacritic rating than Project Origin, 3 months after the second game's release.  (hasn't been 3 months but it looks like I won :-p )
