Dry Underflow FAQ v2

DRY UNDERFLOW FAQ

Q) What is Dry Underflow?
A) A way to achieve "item underflow" in Pokemon Red/Blue/Yellow without the use of a drink item.

Q) Is it faster than the original item underflow method?
A) Yes because you don't have to go buy a Fresh Water so you can skip Celadon Mart altogether. The menuing itself is also a little faster than normal Item Underflow (probably)

Q) What categories does this change and how much time does it save?
A) It saves about 1 minute in Blue NSC and 9 minutes in Yellow NSC. For 151 categories it saves minimal time in Blue (but is still used) and probably a ton of time in Yellow but has yet to be routed.

Q) How do I do it?
A) Here are some detailed instructions for you:

Requirements:
2 tossable items without 255 quantity
1 tossable item with 255 quantity
NO KEY ITEMS IN INVENTORY

Method:
Order items so that your 2 tossable items are in slots 1 and 2 and 255 item is in slot 3
Toss everything below the 255 item
Toss the top two items so you have 3 255 items
Toss all but 2 of the top item (2, 255, 255)
Swap item 1 and 2 (1, 255)
Swap item 1 and 2 again
