I picked up a super cheap 2DS and I was looking for a way to upgrade it to 9.0 so I can use the RAM injection method. It's currently running 8.1.0.19U.
I looked around, and it seems like that if you pick up certain games, you can update your system JUST to a specific firmware. That's what I think I'm getting from such posts, but correct me if I'm wrong. According to 3dsdb, Steamworld Dig (the eShop version) requires firmware 9.0.0.0U. Can I log into the eShop, download that game and will the system only be updated to version 9.0U, rather than 10.3U?
