If you have a modded Nintendo Switch (via Atmosphere or Hekate), you can move beyond the official subscription. Here is how to achieve the "Extra Quality" status.
In the pantheon of retro gaming, few rivalries burn as bright as Sega versus Nintendo. Yet, in a twist that would have blown minds in 1991, the blue blur now lives comfortably inside the red machine. With a Nintendo Switch Online + Expansion Pack subscription, players get access to a curated library of Sega Genesis classics.
But for the segment of the community chasing what they call "Extra Quality" —often whispered about in the context of NSPs (Nintendo Submission Packages, or more commonly, scene releases)—the official emulation is just the starting line.
