I don't have the game anymore, but I imagine like a lot of games there's a version number in the bottom left corner of the start menu. If it is patched it should read "version 1.1." If that doesn't show up, check the eShop if anything's available. It might also give you a banner saying there's an update available if you highlight the game icon in your 3DS's menu.
Plus c cables are still worn easier especially if you rest the cord on your chest or something while replying to emails at bedtime or whatever usb c cords still aren't that durable is what I'm trying to say
