I just got my first 3DS yesterday. I'm planning to get a flash cart for it, currently favoring the Supercard DStwo. On the System Settings screen it says "Ver. 2.1.0-4E". Now I would like to avoid updating the firmware until I understand what the consequences are. I think that if I update the 3DS firmware, the Supercard DStwo would become unreadable and I would need a NDS to boot it and enable the corresponding SCDS2 update. I inserted Super Street Fighter 4 and it asked if I wanted to do an offline update, which I declined. The game worked regardless. Does the SSF4 cart contain the system update? How do I prevent automatic updates? If I enable SpotPass to get the free "surprise" games, will it cause automatic updates to occur? Thanks for your time!
