original story [Fri 31st Mar, 2023 04:45 BST]:
Yesterday we learned how independent developer Ultra Dolphin Revolution gave away 128 free download codes for their Captain U game on Wii U, and it looks like he’s not alone…
Since Nintendo announced the renewal of codes on both the 3DS and Wii U, more developers have joined the giveaway. Game developer Silver Falls also took part, offering codes for the 3DS and Wii U eShop in honor of the upcoming Silver Falls Switch game.
To get one of these old recordings for free, all you need to do is contact the developer directly on Twitter or Discord. You can also earn a second ticket by sharing a photo of your Silver Falls installation and tagging Nintendo on it. Quantities are “very limited” so get in while you can. Here are the games you can play:
Indie developer Astrosaurus Games also announced that it is giving away 100 free codes for the Wii U game Collateral Thinking (attached to tweet below).
If we become aware of any other Wii U and 3DS eShops giveaways, we will let you know. You will be able to activate the codes in both online stores until April 3, 2023. Please be aware that purchases from both of these digital stores have officially ceased.
