I'm trying to use this method but am having some trouble. I've never done ACE or item underflow before so please bear with me.I'm currently trying to obtain the 8F Item using invlid encounter flags (because i have no event that takes an item away and I dont feel like playing the main story all over again…).
Actually you don't need an event anymore. There is a "dry" variation of the item underflow glitch, for which all you need is a stack of 255 X Special. You can get it with MissingNo. using the glitch of your choice. Moreover, if the invalid encounter flag method works, it means the cooltrainer corruption works for you, so that you can encounter a MissingNo. This invalid encounter flag method is obsolete, you should not use it.
The item underflow glitch requires you to have this :

French screen, Special + is X Special and the two first item are useless.
Toss the two first useless items, you will have this :

Toss several 255x of the first item until you only have access to two items. Toss 253 of that first X Special stack and switch item 1 and 2 twice. You should have X Special x0, like this :

Item underflow will be active. Now go there (near Celadon) :

Toss 255 X Special again, and switch the remaining X Special with the Nugget in 35th position. 5 steps right, 5 steps down, 20 steps right and open the item menu to see 8F, that you can switch to a "normal" place (eg : first place). Fly back to Celadon and buy items to fix the item menu.
If you still wanna use the invalid encounter flags, you don't need to USE the attack to trigger the corruption. Just enter/exit the FIGHT menu until it works.
Fact is, cooltrainer corruption doesn't always work, it depends on the values of some RAM addresses. You wil find here TheZZAZZGlitch's methods to maximize the chances. I can tell you that the "renaming party + open unused box" method works very well.
Good luck !
I begin with my item pack in its entirety as follows (just as in the pictures):
Great Ball x1
Parlyz Heal x1
X Special x255
TM09 x3 (It's my understanding that this is not necessary but I did it to match the images in the quote)
I also start in the proper position to the east of Celadon City.
Everything goes according to plan until I'm supposed to swap with the Nugget in the 35th position. While my game lets me scroll past "Cancel," the items listed there all have no name or quantity, and by the time I push "down" 34 times, my cursor has stopped moving. I never see a Nugget. My game then operates extremely slowly and is unresponsive to some commands.
What could I be doing wrong? I'd like to get this method to work since I don't feel like restarting my file to gain access to an event item.
