TL;DR: Skip to “How to choose your flash card” section Why this post This is a reflection of my past 2 months of research on NDS flash cards. I wanted a new flash card to enjoy some NDS games, however, the journey wasn’t quite smooth as I thought. I’ll document the stuffs I learn, so you don’t need to go through what I did. Disclaimer: Every card mentioned below unless stated specifically, I own the card at one point.
