=== Perform dry underflow ===
[[File:Missing_image.jpg|thumb|Step 4: The classic setup for dry underflow. Make sure that at this point your item count is exactly 1. (TODO: Add screenshot)]]
[[File:Missing_image.jpg|thumb|Step 5: The item count is 0 now, so be extra careful here. (TODO: Add screenshot)]]
[[File:Missing_image.jpg|thumb|Step 6: You should be able to scroll down again, even past the 20th item. (TODO: Add screenshot)]]
Now that you have a ×255 item stack, you can save the game and experiment with it if you want to.
{{Explanation|×255 item stacks and the item count|contents=The most notable property of the ×255 item stack is its tendency to [[Item stack duplication glitch|duplicate itself]]. For example, with PP Up ×255 as the 6th item in your bag, toss (or deposit into your PC) the entire stack of your 5th item. Your 5th item is now PP Up ×255 (as expected), but your 6th item is ''still'' PP Up ×255, meaning that you have two of those stacks now. However, if you only had 6 items to begin with, now you actually only have 5 items ''even though you can see PP Up ×255 as your 6th item''. That 6th item will "act like the Cancel button", meaning that you won't be able to scroll past it, and if you press the A button on it, instead of bringing up the use/toss menu, you will exit the item menu.
This may be confusing at first, but just keep in mind that the game keeps track of your '''item count''' (which is supposed to be the number of item stacks you have) and your item list separately. Try not to decrease your item count too much prematurely (although you should be fine if you don't toss, use or deposit from your ×255 item stack unless instructed to). We will be performing '''item underflow''', which means that eventually we will decrease the item count a lot — namely, decrease it to -1, but it takes some careful setup to avoid being stuck at 0.}}
In order to obtain 8F, we want to perform [[dry underflow]], which involves decreasing the item count a lot — namely, decreasing it to -1. For this purpose, we need to make use of a somewhat obscure functionality of the item menu: Pressing the Select button on two items allows you to swap items. Furthermore, if they are the same type of items, those item stacks are combined into one stack instead as long as the total number of items is not more than 99. This decreases the number of item stacks (i.e. decreases the item count) and we will ultimately use this to bring the item count to -1.▼

{{color|red|The below steps may cause you to lose some items from your inventory. In the grand scheme of things that is not that important since eventually you will be able to get any item in any quantity back with ACE, but you do need a few items later (or a bit of money to buy them) to get things going smoothly.}}
Line 112 ⟶ 117:
# '''Make sure to have at least two item stacks above your topmost ×255 item stack. Also make sure that you have access to your topmost ×255 item stack, and it is not "acting like the Cancel button"''' (i.e. make sure that pressing the A button on it brings up the use/toss menu, and does not exit the item menu).
# '''Get rid of all other items above your topmost ×255 item stack''': Deposit all Key items and other things you want to keep into the PC, and toss all unimportant items.
#* Your ×255 item stack should duplicate itself and fill your inventory,
# '''If necessary, start tossing the second ×255 item stack until your item count is 1.''' You will know that your item count is 1 when you are no longer able to toss your second ×255 item stack because it is acting like the Cancel button, and you are no longer able to scroll to your third item stack.
# '''Toss 253 from your first ×255 item stack, so that you have 2 left.'''
#* Your inventory should now look like this
#** PP Up ×2
# '''Swap your first item stack (the ×2 stack) and second item stack''' (by pressing the Select button on the first item stack and then on the second item stack).▼
#** PP Up ×255
#** PP Up ×255
▲# '''Swap your first item stack (the ×2 stack) and second item stack''' (by pressing the Select button on the first item stack and then on the second item stack). They will combine into a ×1 item stack.
#* {{color|red|At this point, don't accidentally exit your item menu by pressing A or B. Otherwise you will be unable to proceed, and the best course of action is to reset the game to load your last save file and try again.}}
# '''Swap your first item stack (the ×1 stack) and second item stack again.''' They will combine into a ×0 item stack.
#* If you've done everything correctly, you should be able to scroll down again, even past the Cancel button and past the 20th item (normally the maximum number of items of your bag). What happened is that you have decreased your item count to -1, but since the game is not designed to handle a negative item count, it becomes 255 instead, giving you access to 255 items. You can now start the next section.
