Ok, it sounds like you are trying to pitch to me what I am already doing and am not happy with. no thats not how I want to do things. My SysNand and Emunand are not connected, and my emunand has 0 streetpasses and 0 games played on it. Instead of trying to convince ourselves its fine the way it is, we should ask for more functionality. More options is never a bad thing, why settle? It would be easy to implement and would satisfy both camps, those that want to use emunand for everything and those that dont. I personally have about 600$ worth of games on my sysnand that I bought, I want to use them and not fake cia copies of them. Therefore sysnand is a much better place for me to play than emunand. like I said, if I didnt have to use emunand for cias I wouldnt. I also have another $350 worth of cartridge games that I bought that I still play in native (non gateway mode) sysnand is my preferred playground.
I guess this discussion answers my question.. there is no better solution than having 2 SD cards... that sucks

I hope the option is added later.. make it something crazy, like hold both triggers and A and Select... something thats hard to do, but I want that option, I am sure there are a lot of others that do as well.
