In The Legend of Zelda: Ocarina of Time, to get more bottles first equip a bottle, in
one of the slots. Then go and find something to put in a bottle (i.e.: Fairie, Bug,
Fish, or anything else you can think of!). Now, hit the Button the bottle is in to
catch the thing and hit start directly after hitting the button. Now select an item you
do not want (Claim Check is good to use after you get the Biggoron's Sword) and
equip it where the bottle you were catching something with was. Press start again
and you will see Link still catching the item. Now you have an extra bottle.
You can have 24 bottles, but then you would not have any sub items!
Note: DO NOT SAVE AFTER DOING THIS OTHERWISE YOU CAN NOT GET
YOUR ''WEAPONS'' OR ''STUFF'' BACK!
