I am trying to figure out how to do the custom licensing because I want to try to port Unreal 4 to the Wii U as a personal project of mine. It is giving me an error stating Epic does not dicuss terms for Unreal 3 source code with public email addresses (trying to use my gmail as I do not have a company as of yet), but I am not trying for Unreal 3. I am not sure how to proceed.
Do I not need a custom license at this time to try porting, or would I only need that when I want to publish something?
It sounds like custom licensing isn’t available to you at this time. But the UE4 EULA doesn’t prevent this kind of project. You say a personal project so I assume you don’t intend to redistribute. You’ll also need to bear in mind whatever obligations you have as a WiiU developer from Nintendo.
