I have found that the controller.ini file must be in the USB drive too. This is not writen in help.
Adeka already gave you an answer but just to clear something up, I'll say that this info is written right there in the first post.
Install instructions
1-4: Download the latest released package and extract it to your /apps/ folder.
or
1. Create a Nintendont folder in your /apps/ folder (ex. SD:/apps/Nintendont)
2. Download the meta.xml file and place it in the same folder.
3. Download the loader.dol and rename it to boot.dol
4. re/place the boot.dol into Nintendont folder.
5. If you want to use a USB controller, select the correct controller file and rename it to "controller.ini". Place this file on the root of the device where your games are located.
