I have compiled pages from Nintendo Power magazine into collections that focus on individual games featured in the Super NES Classic (plus Super Mario 64 to celebrate Super Mario Odyssey). I've done some light editing to some of the images to make them fit better when viewing two pages at a time in landscape orientation. If you use double page view, look for an option in the CBZ app that treats the cover as a separate page. This collection also includes the Nintendo Power comics (the Super Metroid comic should be viewed in single page view).
