I've never played Ocarina of Time, or even seen it before. However, I recently saw a TAS of Super Mario Land, where Mario completes the first two levels, then dies, spends a few minutes falling through screenfuls of random garbage, and then suddenly ends up at the endgame scene.
I thought it was hilarious, even though it doesn't show you what the normal gameplay is. That's the point: TASes aren't intended to show normal gameplay, that's what Let's Play is for. TASes often skip parts of the game, do them in the wrong order, or just wreck them completely.
So I don't see the language as a problem for this TAS, because even if it was in English, I wouldn't be able to make out the story from the TAS anyway. The
rule is that you don't beat a record if switching language is your only improvement (e.g.
this) but that's not the case here. "We prefer English ROMs" has always been a guideline with exceptions.
So a definite
yes vote for me. This is an impressive piece of work.
(yes, it's one of those games that goes on forever, but it has six distinct rooms, so completing every room once on the hardest difficulty would be a goal worth seeing)
