This program takes The Legend of Zelda: Ocarina of Time and randomizes the locations of the items for a more dynamic play experience. Proper logic is used to ensure every seed is possible to complete without the use of glitches and will be safe from the possibility of softlocks with any possible usage of keys in dungeons.
The items that randomize currently are all items within chests including those in grottos, items given as rewards by NPCs including from minigames and Deku Scrub salesmen, the items given by freestanding Pieces of Heart, Heart Containers, and Keys, and the items obtained when getting the Bottle and the Fire Arrows at Lake Hylia. All dungeons will always have the same number of Maps, Compasses, Small Keys, and Boss Keys they had in the original game, but which chests within those dungeons have those things is random. The item pool will contain a Biggoron Sword that will not interfere with Medigoron's sale of the Giant's Knife (which is always vanilla), and a randomly selected adult trading quest item other than the Odd Potion will be somewhere in the item pool.
Certain types of items are now "progressive", meaning that no matter what order the player encounters these items they will function as a series of upgrades. The following item types will be progressive chains:
-Hookshot to Longshot -Bomb Bag to Big Bomb Bag to Biggest Bomb Bag -Goron Bracelet to Silver Gauntlets to Gold Gauntlets -Slingshot to Big Bullet Bag to Biggest Bullet Bag -Bow to Big Quiver to Biggest Quiver -Silver Scale to Gold Scale -Adult Wallet to Giant's Wallet -Deku Stick Capacity Upgrades -Deku Nut Capacity Upgrades -Magic Meter to Double Magic
To be more clear about which NPC items are shuffled, it's only the one time permanent item rewards for the most part like NPCs who originally gave Pieces of Heart or inventory items. The only exception is that even though in vanilla the reward for 40 Gold Skulltulla Tokens was just 10 Bombchus that is still a randomized reward in randomizer (but the 200 rupees for all 100 Gold Skulltulla Tokens is not randomized so the most tokens that could be required to complete a seed is 50). As a mercy to the player, the Ocarina Memory Game in the Lost Woods will start on the final round as that minigame was very long originally, the three day wait on the Claim Check is removed, Bombchu Bowling will have a fixed sequence of prizes that is of maximum convenience to the player, Dampe's Gravedigging Tour will always be won on the first dig, and the fishing minigame is made much simpler (8 lb fish for child now, 10 lb for adult). Additionally, any NPC who gives a trading quest item either for the child or for the adult other than Anju's initial gift as an adult does not have a randomized reward, and as a design decision, the Fairy Ocarina and Ocarina of Time are not randomized.
A special note is needed for the six Great Fairy Fountains scattered across Hyrule. All six of these fountains now give random item rewards, and the magic and life upgrades can now be found as normal items scattered around the world. Happy hunting!
