The Super Mario Bros. Wonder Nintendo Switch 2 Edition Upgrade Pack brings a technical and content refresh to the action-adventure experience for the Nintendo Switch 2. This cartridge-based upgrade requires the original full version of the game to function, adding 5.1 GB of data that enables 4K resolution when docked to a compatible TV. You will notice a smoother feel during gameplay thanks to frame rates capped at 60 fps for 4K output, along with faster load times that keep the momentum going. Beyond performance, the pack introduces the Meetup in Bellabel Park, which features dedicated multiplayer attractions and seven new boss courses where you can face the Koopalings. The playable roster expands to include Rosalina and Co-Star Luma, the latter of whom supports mouse controls via the Joy-Con 2 controller. You can now equip Dual Badges to use two effects at once or utilize the Super Flower Pot to take on a flower form. For those who prefer a more relaxed pace, an Assist Mode provides immunity to damage and recovery from falls. Social play is expanded to support up to four players on a single system online, with the ability to see up to 11 live player shadows in your course. The game also supports local wireless, LAN, and GameShare, while remaining compatible with Super Mario series amiibo for various decorations and power-ups.
