Does this also work for the American version of the special edition?1. Update Luma to v7.0 or higher, enable "Enable game patching" in your Luma settings.
2. Download the zip in the first post and make this folder path: SD:/luma/titles/TITLEID/romfs.
3. Then navigate to (I'm assuming you're using the US SE despite it being region free) NTR CFW Version/USA Special Edition/fefatesSE.
4. Copy the GameData and Scripts folders to your romfs folder.
5. Start the game.
Replace TITLEID with the Special Edition's title ID.
