I would like to know if there is a tool that can recover Pre-ordered content (DLC), since I have sought support on the official pages of Pokémon Japan and Pokémon America. They explain to me that "mystery gift" codes only work once. The saddest thing about this situation is that the DLCs are kept in the "save file or files" and are not linked to the Nintendo account.
Last week I decided to start a new game and for my surprise I lost all the pre-ordered content, so I felt very screwed. Luckily I left a copy of my previous "save or save file" in PKHex. Someone could create a tool to obtain the DLC via PKhex and be able to use it in a new game.
If my save file could be used for this purpose since I have all the DLCs, such as wallmart, secret club of Japan, the golden backpack and others, including the new Pikachu and Eevee clothes of the season pass.
Thank you.
