Getting 0 turns in a battle using glitches (Mario+Rabbids: Kingdom Battle)

I am doing some testing on 1.0 with a Japanese cartridge (yes, there are differences between American/European and Asian) and found a lot of interesting stuff, most of which I will look into a bit more before sharing. But I thought I'd share this discovery now:

It turns out in this version you can enter story-chapters through the Washing Machine from World's you have not completed, including story chapters you have not completed.
So far I have only been able to do it for World 1, but it might work for others. To do so simply beat 1-1 and get your World progress past World 1 without beating it (e.g. with skip to World 2/4 and chapter transfer or by simply beating 2-1/4-1).
Unfortunately beating a chapter through the Washing Machine does not seem to count towards the actual in World progress, however there are still some neat things this enables.

You can transfer World 1 Washing Machine battles to any World 1 chapter. Previously it was only known how to transfer non world 1 battles to 1-1 and 1-2
Notably you can transfer a World 1 battle to its own chapter counting as a later battle. This lets you complete battles in 0 turns (according to the Washing Machine). While it is already possible to remove battles from chapters entirely, I find this fascinating nonetheless.
You can easily get past battle triggers, from chapters that have mandatory puzzles (the only chapter that has mandatory puzzles in world 1 is 1-8) This let's you get to the world 1 boss arena early, sadly it is while being in chapter 1-8 and the 1-9 battle does not trigger if you do that.

The basis for this is, that if you enter a chapter through the Washing Machine while World 1 is uncompleted, then enter a battle in that chapter and restart the battle you will get moved to the spot of your actual in World progress, thus letting you escape the confines of the chapter without actually exiting the chapter.


In this video I show how to get a battle with 0 turns using this glitch.
Here is the step by step process:
Play on 1.0 JP
Get your World progress past World 1 without beating it
Progress World 1 to right before 1-8
Enter 1-8 through Washing Machine
Play to 1-8-3. Make sure the 2 mandatory puzzles up to that point are solved.
On 1-8-3 restart the battle. You should now be standing in front of the 1-8 chapter banner
Play through 1-8 (When you encounter a mandatory puzzle it should be solved. Un-solve and then resolve it)

If you want to explore past 1-8 do not un-solve the puzzles and just walk past them. You will notice that the battles won't trigger. Now you can explore a bit. However the blue wall at the start of the chapter is still there.

I hope you enjoy the video!
