Guys I got a Supercard DS2 and it's great. I love it. But the thing is i can't ever put it to sleep while I'm playing a game. I can't even leave the flashcart in. You know this is true because the DS2 drains the battery. Now not a big problem, but I do sometimes wish that I could play a backup off DS2 and resume my game without having to eject the flashcart, go through home screen, etc. every time. With R4i Can I just close my 3DS while playing a game and then open it back up and be where I left off without draining the battery? What about just leaving the cart in, will it drain the battery?
