Moin,

after the shocker that was today, we'd oughta bring you up to speed (lol pun) what's been happening the past day for Swap Mode.

A major trick was discovered for Swap Mode (1P and 2P) titled Dora.

In short on how it works: In Swap Mode, if you start running (has to be Mach 3 or higher if Player 1 is playing Gustavo), taunt and press up and down on the same frame when entering a door, level gate, rocket or taxi, the state usually applied on the first frame of entering any of these, is overriden by the taunt swap transferring states between the two players. (thanks to vani for the writeup)

Essentially, Dora is a highly versatile trick that will most likely shake the entire route for Swap Mode for both 1P and 2P categories. The trick Dora itself is not banned for Unrestricted or NMG, and may be used in either. However, Dora allows for an even crazier trick where we must take action: Progression Transfer.

It sounds exactly as scary as written out. Dora allows any progression item that count towards your overall % (toppins, secrets, treasures) to be collected in one level, and be "carried" over to a completely separate level.

As a result, the latter level will have the progression item unlocked, despite entering an entirely different level beforehand.

Effective immediately, Dora may be used in NMG with the exception of Progression Transfer. Unrestricted is not affected by this.
