Blue Warps and Changing Items

[jiano]

How do you control where a blue warp takes you? Just putting the actor down crashes the game, and I can't figure out how to change the blue warps that already exist in the game.

Also, is there any info on how to edit items? For example, in Zelda's Birthday he made the Megaton Hammer usable as a child. How is that done?

Any info is appreciated.

I have tried using the blue warp as well and while it doesnt crash my game, the warp never loads. So I would be interested in this as well. I believe the hammer can be ported over to young link, though the animations required for it may be complex.
