    Bought a GW card, and played a bit on it. Now, i want to install EmuNAND on it, but

    is there a way to do that, while keeping my ROM Save data (and possibly retail save data)?
    Do i need 2 SD cards? (Got 1 4GB card that came with the system)
    Are there any risks of bricking the 3ds (like downgrading)?
