Beta worlds for Zelda MM

There is a cheat for Zelda MM called "Press L for beta world 1". Does it really work?. I press L (after setting it on and select a beta world, obviously) but nothing happens. I'm using the (U) version.

Beta Worlds for MM

Thanks! The code really works, but its notes are from a former code called 'Walk through doors' or something so. Besides, the codes' descriptions do not match the real places . Here is a list of the codes currently in the cheat, the [bracketed] are the plaches the cheat really took me:
