As of the 4.0.0 Update, which originally brought USB headphone support to the Switch, it was discovered that, via the use of the Wii U's Gamecube Controller Adapter, that almost every Switch game can be played with a Gamecube Controller. However, since the Gamecube Controller lacks a left Z-button the player does not have access to all of the controls of games that normally would utilize the Switch's ZL button.
