Aren't there 3 Realm of Memories levels? There is a original Legend of Zelda level, too, right?

Yep, that's new. Once you've beaten all the levels and unlockable levels, go back and rebeat the 3 original levels to gain gold keys, and you can enter a different part of Vaati's castle for a different final dungeon. After THAT, go back and beat them a third time to get to the third and final final dungeon.

There's a hard-to-spot passage leading to the right at the south end of the area you start in. Also, there's an even-harder-to-spot passage at the north end of that area, which leads to the bombs. I got stuck there for a while.

Can you save in this game? If you can, can someone tell me how?

Beat the boss/stage.

You can't save mid-level?

It auto-saves after every dungeon

And we only have 3 of 'em. At least, at start.

Indeed, at the start

Uh, what are dungeons exactly? The stages don't exactly have a name.

The whole stage.

Unlocked the Hero's Trial! I'm sure this will get me the hurricane spin.

It's primarily a multiplayer game, and the object is to get the most rupees in a stage, so that wouldn't make much sense, would it?

The second door in Hero's Trial is insane! Every few feet there's a two-person button that unleashes a mob of enemies on me. When I defeat them, a second set of enemies appears, and sometimes even a third! Imagine getting mobbed by a swarm of strong enemies twice and defeating them, but just barely. You think it's over and a third set appears, finishing you off. It's not that bad the first 5 or 10 times, but it does get to you after a while!

I just failed in the Final Floor of Hero´s Trial Level 2. It´s insane, army of mummies attacked me. I´ve finished all Zelda´s to date (except Zelda 1 and 2) and I have to say that Hero´s Trial is easily one of the hardest challences in the series.

There's a hard-to-spot passage leading to the right at the south end of the area you start in. Also, there's an even-harder-to-spot passage at the north end of that area, which leads to the bombs. I got stuck there for a while.

Still can't find it...there seems to be an uncrossable ravine both north and south, and I've kept n walking all up the right hand wall...nothing.

Nvm figured it out. forgot you could throw your partner

This is exactly where I died! I had actually gone very far in it, too. I think it may have been one of the last fights.

I just downloaded this this morning, but this game is amazing! Never played it before because I never owned a Link Cable, but this game is so much fun!

I never got to play the original version (lack of game links and game packs) but this is awesome!
I got a friend to play with me (he used my DSi), even having to carry him when he wouldn't listen to my calls was fun!
_{And trowing him to lava pits was lots of fun too-}

I already beated the realm of memories, it was awesome, specially the LA and Zelda 1 levels (gotta love how the graphics for everything match the styles of the games).

I'm on my way to unlock the Hero's Trial, hows that one?

The first stage is manageable, but the second one is hell. I tried my best but I eventually ran out or ruppees near the end.

Sometimes the game starts me in an area I'm trapped in because I don't have the right item. I sometimes can't progress because of this too. Any help?
