Pretty much the Pro Controller minus the $40 extra $ the Pro Controller costs. Works well on lots of games (except Splatoon and Zelda)
You can connect your GameCube Controller with any WiiU adaptor, even the Mayflash and the other one that is like $17 on amazon right now. Also any gamecube controller works, even the wavebird. Also you can connect up to 8 GameCube Controllers
Ok so for many people, going into "Change Grip/Order" does not work, so the easiest way to set it up is to
1) Go to controllers from the main menu (using joycons or Pro controller)
2) Select "Find Controllers"
3) Play around with the "Find Controllers" area for a little bit and then exit.
4) Now go to "Change Grip/Order"
5) Press L and R on your GameCube Controller. It should pop up.
You're all set and ready to go! Gamecube controller works great on Mario Kart, Sonic, Shantae, FE Warriors, NBA 2K18, etc
