Nintendo recently announced that anyone who bought Shin Megami Tensei IV and Fire Emblem: Awakening and registered them through Club Nintendo would get a $30 eShop credit. Unfortunately, anyone who downloaded the digital version of Fire Emblem before linking or creating their Club Nintendo account cannot automatically register their game, preventing them from partaking in the deal.

Since I happened to be one of those people, a quick Google search revealed I was definitely not alone.

After some digging, it turns out the only way to register your previous downloads with Club Nintendo is through the following steps:

1. Call Nintendo’s support line at 1-800-255-3700.
2. Once you’ve selected your language, press 3 to speak with a eShop customer service representative.
3. They’ll need the serial number on the back of your 3DS.
4. They can then manually register any game you’ve ever downloaded.

If you’re sitting in front of your computer during the call, you can refresh your Club Nintendo account, and the survey for Fire Emblem and the $30 offer should appear immediately in your to-do queue.

After you’ve linked your 3DS or Wii U to your Club Nintendo account, any future downloaded games will automatically be registered.

For those unfamiliar with Club Nintendo, it’s a pretty interesting service that rewards customers for registering certain games and taking surveys about why they made the purchase. Completing a survey for eligible titles or hardware rewards coins, which you can then use to get unique rewards. The surveys also seem like a great way for Nintendo to gain insight into people’s buying habits. For instance, “Did you know about this promotion when you bought the game?” is a survey question for both Shin Megami Tensei IV and Fire Emblem, so it’s possible that if the survey proves the deal was successful, we may see more like it in the future.

The $30 eShop promotion ends Aug. 31, and you must register both games by that date to earn the credit. Nintendo is developing a Shin Megami Tensei X Fire Emblem crossover title, which may explain the unique promotion.
