Updated after your update: In this case I think we can assume "acceptable quality" has already been established by Nintendo's QA department. Its not an open store after all.

They've actually published games with Nintendo before, so they discuss how such terrible games were allowed on the shop in the second video
If you take a game back to a major retailer like Target or Big W, they won't accept it with the seal broken unless you tell them there is something wrong with the physical disk or cartage. They won't accept a return if you just tell them you didn't like it. (in my experience - also not an expert on this either)
The Nintendo online market pretty much has no oversight anymore. They don't do any careful pruning of shovelware these days.

NES games often had some pretty rough translations, but I can't think of a single game in that era that was this garbled.
