Star Fox 64 3D was finally released at Japan two days ago as us Americans still have to wait till September to experience arguably the best remake on 3DS (Once again, its better than Zelda OOT 3D). The graphical facelift is pretty outstanding now that I have seen some full levels in action from Zoness, Solar, and Macbeth. The control preferences will probably be a personal thing as some would enjoy the gyroscope controls, but I think playing without them seems to be the way to go especially going for medals. The music has been also remastered for all the levels as they sound for the most part, but I wished there was an option for the old music as well. I'm not sure with the Japanese voices if they're the same as the original, but the other sound effects still sound the same though. Anyway, here's part of a full playthrough above even though the quality is not as great, but of course it can be hard to record 3DS stuff without proper equipment.
UPDATE - Here's a full playthrough of the game in direct feed quality. (spoilers I guess if u haven't even played the original at all yet)
