I use three 200gb micro sd cards. They are all formatted the same exfat. I copied everything from the original sd card except the Nintendo folder to the other cards and have working great.
--------------------- MERGED ---------------------------
All game icons appear no matter which sd card I use, but must switch to the appropriate card that contains the game that I want to play. One card contains first party Nintendo games, second card contains third party small capacity games like dead cells, the messenger, etc..., the third card contains third party large capacity games like doom, Wolfenstein, etc...
