On 3/25/2021, the only Nintendo platform for which new development is possible will be Nintendo Switch.
Development for Nintendo 3DS and Wii U will only be possible for those who have already purchased development hardware.
Those who do not have development hardware will not be able to develop.
In addition, when developing for Nintendo Switch, you must apply after you have registered on this website.
You will be able to access the information necessary for development for Nintendo Switch only when your application has been approved. We ask those of you who wish to develop to apply after you have registered.
(Please understand that it will take time to review your application.)
