THIS ONLY WORKS ON US GAME BOY VERSION, NOT JP OR PAL OR 3DS

there is a new glitch that instantly ends any duel:

You press Down+A on the same frame, while viewing the play area, with cursor on your bench (or your active, if you have no bench).

Thankfully due to lag frames, it is not frame perfect by any means.

One way to do it, if you have no bench, is to buffer the Down+A immediately after pressing Select. However, you CAN'T hold Select during the buffer or it won't work. So tap Select (I recommend having it bound to a Left Trigger), then hold Down+A.

If you have a bench, the best way is to open a Pokemon's info, then buffer Down+A while closing it (holding B is OK for this)

Sometimes, instead of winning the duel, this will take you to an infinite party screen. Pressing B to close it just reopens it. This is fine, and actually makes the trick easier. Buffer just A when closing the screen. Eventually, it will work. (Whether the duel ends or not is based on some subframe Game Boy screen refresh timing things by the sound of it)

In this example, all of these attempts were the correct input, just none of them worked:

Hope this works as a basic tutorial for the input needed

BIG NOTE: The only reason you win the duel like this is because by default you are the "last duel winner". If you lose a duel, this trick will just copy that loss. Saving and reloading doesn't change this, you'd have to win a duel to change it

CURRENT ROUTE: Choose Bulbasaur & Friends due to having the bulkiest basics

There are two club orders that have been timed to be identical theoretical lengths (world map inputs below)

Mason Fighting Grass Water Lightning Rock Ishihara Fire Science Psychic Grass Fighting Dome: Right, right up, down, left up, up, up, right right up, right, left, down, down left, up right

Mason Lightning Fighting Water Grass Science Fire Psychic Ishihara Rock Fighting Grass Dome: Up, down, right, up, up, up, left, left up left, down, down down, right up, left left

The Lightning-first saves some movement thanks to Ronald pushing you to the right, although you have to take an extra step when leaving Water so you exit on the left (for Ronald 1). Always fight the right guy in Lightning Club after Jenny, since Isaac is on the left half. Minimize step counts by fighting opponents on the left side before the right side in Grass Club and Water Club (Grass should go Brittany Kristin Heather Michael, Water should go Sara Amanda, Jessica before Ken) Of course, its up to you, the extra steps aren't that big of a deal and can feel less natural.
