I really don't have a way of recording it, but you can try it, it's not difficult to test. So I found this neat trick, probably useless in any run, if you jump while riding Koraidon you can move in the air. Now, because of how the game handles falling down hills and mountains, you cannot jump multiple times while trying to climb (without the ability). When falling down, on the other hand you can jump. So, having that in mind you can: -Go up against a not-that-steep ledge (You have to be able to slide going up) -Jump facing away from the ledge -Immediately turn your input on the opposite direction and spam jump, seeing where you can climb next.

Additionally, make sure to store the games on your internal storage and not an SD card, as these also have longer load times. You can move a digital game
