Here is something surprising. The Nintendo Switch Firmware update 3.0.0 has made the Mayflash GameCube Adapter compatible with the Nintendo Switch. This is surprising as Nintendo’s own GameCube adapter is not Switch compatible yet.
This is likely due to the update also making the Pokken Tournament fightpad compatible, and this does provide some interesting opportunities. Maybe its time to pick one up for when Nintendo brings GameCube games to the Switch eShop? Or maybe it might be good to use this for Pokken Tournament? Or could this be a sign that Smash is coming? We will have to wait and see
