If we're on the subject of logic for a glitchless randomizer a la ALttP, I think we would need to be able to determine what items (at a minimum) are required for each dungeon. Here's what I can think of off the top of my head, assuming that the Door of Time is removed in some fashion. If there is something that I'm forgetting, put it here.

Stuff that most likely should not be randomized, except possbily with each other -Heart Pieces and Containers -Gold Skulltula Tokens -Child Trading Sequence Items (except for Goron, Zora, Gerudo, and Truth Masks) -Adult Trading Sequence Items (except for Biggoron Sword) -Bottles -The Master Sword

Child Forest, Requires one of the following combinations -Sword, Shield, Fire Source, Slingshot (For Deku Tree) -Bomb Bag/Bombchus (Goron City exit) -Silver Scale/Golden Scale (Zora's River exit)

Beating Dodongo's Cavern requires the Bomb Bag or Goron's Bracelet (King Dodongo), Slingshot, a Fire Source, and possibly the Sword. There's also the possibility that this dungeon could be beaten as an adult, but I'm not sure if this is true or not.

Beating Jabu-Jabu requires the Ocarina w/Zelda's Lullaby or the Scale (to get into Zora's Domain), the Letter bottle (at a minimum), the Boomerang, and the Sword. I believe Slingshot would only be required if you didn't already have Boomerang.

Beating Forest I believe only requires Sword, Hookshot, and Bow.

Beating Fire I believe requires Sword, Bombs, Megaton Hammer, Hookshot. Goron's Tunic would also be useful, but I believe there are enough safe areas that it is not absolutely required.

Beating Ice requires a weapon and a bottle.

Beating Water I believe requires Sword (at a minimum for Dark Link), Longshot, Iron Boots, and Bow. Similar to Fire, Zora's Tunic would be useful, but I do not believe it is required.

Beating Well requires Sword, Ocarina with both Song of Storms and Zelda's Lullaby, and a Fire Source.

Beating Shadow requires completion of both Fire and Water (so you can get the Nocturne of Shadow), Ocarina w/Zelda's Lullaby, Hover Boots, Sword, and a Fire Source. While bow would be useful (for fighting Bongo-Bongo and for destroying the wooden spike wall in the Big Key room), it is not required; though you would have it at this point due to having beaten Water. Lens of Truth, I believe is, also not required but useful.

Beating Spirit requires the Ocarina w/Spirit's Requiem, Lens of Truth (for the Phantom Guide), Sword, Longshot, Mirror Shield, Megaton Hammer, Boomerang, Bombchu, and a Fire Source for both Adult and Child Link.

Beating Ganon's Tower requires Master Sword, Bow w/Fire and Light Arrows, Hookshot/Longshot, Golden Gauntlets, a bottle, and Bombchu. I believe that useful, but not required, items are the Lens of Truth and the Goron Tunic.
