Wii U owners were extremely excited about the release of Super Smash Bros for Wii U not only because one of the best games from the GameCube generation was making its way to the semi current gen but because releasing with it would be a great adapter. It’s often said that the best controller for Super Smash Bros is the original GameCube controller so when Super Smash Bros. Brawl was released on the Wii there were no issues because the Wii had GameCube controller ports. But when the Wii U was released those ports had gone missing. Nintendo however released an adapter that by way of two USB ports would allow Wii U owners to use their GameCube controllers for Super Smash Bros. Wii U. Well now the Emulation community has gotten a hold of this adapter and the extremely popular Nintendo GameCube and Wii emulation software Dolphin now supports perfect 1:1 controller mapping.
It didn’t take long after the release of this new adapter for the emulation community to reverse engineer it to work with PC’s and even shorter for the Dolphin emulation crew to fully support it. This is great news for those looking to play all your favorite GameCube or Wii games on your PC without the need of finding and purchasing a used GameCube or Wii console. There is however a guide one will need to follow and this can be found on the Dolphin Wiki.
From the moment that it was announced, this was one of the most potentially game-changing accessories for Dolphin. When it hit, it was rife with shortages, and didn’t natively work on PC (which was expected.) Thanks to reverse engineering work by shuffle2 andtoadking, within a few days the adapter was functional on computers and drivers were coming.
While there are generic programs and drivers to get GameCube controllers working with any emulator, including Dolphin, skidau decided to take it to the next level, skipping over pretty much all of those steps.
He added native support for the GameCube Controller Adapter, which means that once it’s setup all you need to do is have it plugged in, and Dolphin will auto-detect the adapter. This allows users to get 1:1 joystick input compared to the GameCube and Wii. No more wonky deadzones, no more messed up R/L triggers; everything will work just as it does on console without the hassle. Fortunately, F-Zero GX has a controller calibration test which lets us show how accurate various controller set ups are. – Dolphin Blog December
Now the only issue is getting a hold of the very popular GameCube controller adapter. Good Luck!
