Despite having a memory card loaded in slot A, I couldn't find my Metroid Prime 2 save file on it. Turns out that Nintendont was set to emulate the memory card and is saving to the SD card directly. I also can't move that save to the memory card, apparently. I have a 59 and a pair of 251s on hand, but since Nintendont is using the SD card is there any need to keep these cards? I can switch off emulation and use them but it seems almost a waste if they won't be needed.
