How do you extract character sprites?

Previously, I manually took screenshots while playing the game, then removed the backgrounds in Photoshop to extract each image individually.
That was extremely tedious. I saw in a YouTube video someone easily extracting only the character from the game screen.
I’d appreciate it if you could explain how to do that. Also, is there a way to extract sound files or backgrounds separately?

there are many ways, but depends of the system you are talking about.

As @O Ilusionista said, it depends on the game. There's no universal method that works perfectly on everything. Neo-Geo games tend to have debug modes that are make extraction a breeze. Other games may or may not. Many arcade games will - but most console games don't, and you have to set a workflow specific to the game.

The video is probably one I made. It was done through Photoshop actions, first filling unwanted colors with a solid single color, then selecting the remainder from it.
