How much time does it take to go from the final hit of a boss to the start of another character's classic mode? Is there any loading differences between the cartridge and digital versions? Kind of random, I just need to know for research.

Do I submit the in-game time, or real time?

I want to start recording runs for this game but, I don't really have a way of doing so at the moment.

Could I get suggestions on some of the best ways to record footage on a New Nintendo 3DS XL?
