Help setting up Mayflash GC Adapter

[ZackDaTitan]

I've looked everywhere online and any articles found did not work for me, how would I set up my 4-port USB Wii U Mayflash Gamecube adapter to be used as a controller for N64, mainly Smash 64?

Please do not post a support request without first reading and following the advice in https://retropie.org.uk/forum/topic/3/read-this-first. In addition to that information, what problems are you running into with the adapter exactly? Are you running it in USB mode or WiiU mode. The prior should just work and the latter can be made to work using this driver.

@mediamogul I looked but no instructions were posted on the driver download page

I adapted someone else's tutorial that I can no longer find online from some notes I took a while back.

From the command-line, enter:

git clone https://github.com/ToadKing/wii-u-gc-adapter
cd wii-u-gc-adapter
make
chmod +x wii-u-gc-adapter
sudo cp wii-u-gc-adapter /usr/local/bin
sudo chown root /usr/local/bin/wii-gc-adapter

The above commands will build the adapter driver, make it executable, and move it to a standard location.
Next, you'll need to make a basic service file to allow the driver to run on boot (and as root):

sudo touch /etc/systemd/system/gamecube.service
sudo chown root:root /etc/systemd/system/gamecube.service
sudo nano /etc/systemd/system/gamecube.service

Paste the following and save:

[Unit]
Description=Wii U Gamecube Adapter
Before=systemd-user-sessions.service

[Service]
TimeoutStartSec=0

ExecStart=/usr/local/bin/wii-u-gc-adapter
User=root

[Install]
WantedBy=multi-user.target

Then to enable and start the service:

sudo systemctl enable /etc/systemd/system/gamecube.service
sudo systemctl start gamecube.service

Reboot and check that the service is running:

sudo systemctl status gamecube.service

You should get something like this:

gamecube.service - Wii U Gamecube Adapter
Loaded: loaded (/etc/systemd/system/gamecube.service; enabled)
Active: active (running) since Wed 2016-03-16 23:08:34 EDT; 11min ago
Main PID: 363 (wii-u-gc-adapte)
CGroup: /system.slice/gamecube.service
└─363 /usr/local/bin/wii-u-gc-adapter

@mediamogul I will try that definitely, does the adapter have to be in Wii U mode or in PC mode?

I figured it out (Wii U), thank you so much!
