I'm wondering what the best way to prevent a game save from writing to the SD card would be. It is known that game saves with Gateway aren't stored every time the game saves (It occurs when you exit the game and also if you power off the 3ds during gameplay I believe?). This can actually be useful while playing games with resume data (One-time use only saves), or with games that force you to save or overwrite data. Currently I'm just ejecting the Gateway cart. This kicks the device out of emuNAND, which is a slight inconvenience. A safe way to reproduce what I want is simply to back up the save from the SD card so that I can restore it if I need to - but this takes way longer since I need to remove the SD and reboot the 3DS and stuff. I don't know if taking out the flashcart while a game is running is safe for the cart or console. If I knew, I would have peace of mind.
