Q: How did you get Pokemon in such good quality?
A: On the 20th anniversary of the Pokemon anime series they did a re-scan of the first episode and shipped it with the 20th movie japanese Blu-Ray. In my opinion this looks astonishing.

This video has no AI upscale, no interpolation, none of that shit that ruins the video quality.
