I have followed WindPower and it works. Thanks so much! However, I found that the save doesn't have titles (Example: Chapter 1: Nohr) because of the name patch. If someone knows how to fix it, please inform me.
For now, I use the undub patch + Swimsuits patch + Fire Emblem Fates Undub Resync by sataneku.
Not using the name patch because of the issue above and because the patch doesn't work in the DLCs.
