Translation?

I don't think so. Well at least not for n64. The only thing you can do is get a different region of the game or put up with it.

I didn't see any from jap2english

But there are some from english to:
-portuguese (zelda OoT (100%), zelda MM (12%)
-italian (zelda OoT (100%), and some more simply games)
-russian (zelda OoT (80%), zelda MM (10%), most complete translation (not only text, but some graphics, also compressed graphics too, by me...)

all patches available at zophar domain.

If there are any editors exists for compressed stuff in n64 roms... - there would be translations. But no editors - no translations. Only zelda is translatable, as I know...
