There is a better way to play DS and 3DS, but it is not cheap. It’s called Galaxy Fold. Just saying.

3 hours to set it up? Between that and other things you mentioned, it sounds like you need to learn how to use Windows.

I never understand why people rush out of planes. They specifically tell you to take your time and double check your stuff. Even when making a connection, there’s no reason not to double check.

It sucks, but I hope you learned a lesson.
