(Very minor *SPOILERS* for Tetra's Trackers are contained below)
Tetra's Trackers, a fun game, was cut from all non-Japanese releases of the game.
Coming from someone who played it (and it is *quite* fun, I must say) - the game is very dependent on the commands that Tetra, Sue Bella and King of the Red Lions give you - in fact, had it not been for a rough translation guide for the game (over at GameFAQs.com) I would have been quite stumped as to what to do (since I speak/read absolutly *no* Japanese).
But... I don't see any reason as to why the game couldn't have been translated - it's not like the game was heavily dependent on the Japanese culture or some such. No, I think the reason that the game wasn't brought over to the US was because NoA didn't want to commit the resources to translating the game since... well... Let's put it this way, while I enjoyed it as a fun destraction, most of y'all probably wouldn't have. It's not Zelda in any way, shape or form and is very much a "party game" or such. It's a race/competition with Link as the main character - and that's pretty much it.
