Okay So I've been using Nintendont for about a year or two and I was pretty far in Super Mario Sunshine but when I went back to play it, it said no memory card had been created. Even my Animal Crossing, Sonic Adventure 1&2, and Zelda: Four Swords Adventures save files are gone! What happened. I didn't delete anything in the folders. I only switched between 59, 123, and 251 memory card blocks. Did that erase my saved data? I found the BCA file for Super Mario Sunshine (GMSE) and it was created on January 2, 2015 but last night I started a new file on another memory card and now I'm all confused and don't know how to get my old saved data back? It says "GMSE01.bca", what's that? I also found the save files to Sonic Adventure 1&2 and Zelda: Four Swords Adventures but that's it.
