Is it possibly for the Gateway 3DS team to allow rom files to have online features working? Also, if I use a retail cart that has multiplayer (meaning I need the latest firmware) in emunand. Where does my save file for that retail cart go? Onto the card? And does that save file only work while I am in Gateways emunand? Could I not just take that retail cart and use it in a 3DS with the latest firmware for online? Thank you.
