I wont lie, i remember those coloured ketchups, and i remember not wanting to eat it because it was funny colours and i figured it would taste gross but anyways..
I dont think MC is after WW because of the artwork, that wouldent make sense, i just personally believe that Link leaving on a sailboat that looks just like the one from LA seems like more than a coincidence, im not trying to start anything here.
OoX was made by Capcom, not by the same company that made all of the other Zelda games. Capcom is not nearly as involved in the Zelda series as is the companies who makes the other games. chances are that Capcom reused ideas. we see the same monsters, the same townsfolk and the same bosses being reused but that doesnt affect the timeline so much so why does the fact that one sail boat looks like another affect YOUR timeline?
the creators have told us, in print, that LA comes directly after ALTTP. i understand that you think they contradict themselves but if OoX came before LA like you said, then they would have told us, IMO. my advice is that rather than spending a lot of time trying to figure out something that the creators say is wrong, you should just go with what they say is right and drop it.
