Is it possible to extract sprites from Secret of Evermore?

No. None of my tools would be useful for modifying existing games. They are intended for generating new content for original games.

Probably could/should have done that meme using Mode 3, and then you could have used 256+ colours in the image. Nobody would have cared still, but, dang, the image could have looked pretty awesome: https://inceptionalnews.wordpress.com/2022/10/23/snes-mode-3-images-can-look-gorgeous/ 😉

Good point. It would look better in Mode 3. However, this is just a demonstration of my Mode 1 tool, to show that you can now import an image.
