I was on 9.9 emunand and decided to update my emunand to 10.3 and use the newest 3.7 release of the gateway 3ds launcher.dat file. when i first choose a game using the gateway menu with the select button it seems fine but when i want to switch games i get this error message, "This Game Card cannot be read. Please remove and reinsert the Game Card." Never had that problem with 3.4.1. Is this normal on newer gateway launcher.dat past 3.4.1?
