Most of Switch's previous official emulators have been fine, though fairly barebones, with minimal filtering and scaling options. They were also preserved for the Wii U Virtual Console version of the game, but it's excellent to see them continue to be available. Those levels are automatically unlocked here. 3 supported the old e-Reader accessory, allowing you to scan in physical cards which would unlock brand-new, original levels for the game. There's another place where Nintendo went above and beyond, too.

With the filter on, the flicker remains consistent, leaving the chain simply looking transparent - just as it should.

With the default screen mode, the chain appears to go in and out of a flickering state every few seconds as the timing goes in and out of sync. As Jordan Starkweather notes on Twitter, you can quickly see the difference with the Chain Chomp in Link's Awakening. Turning on the Game Boy screen filter also causes those games to run at their native 59.7 frames per second.
