maybe, but that's the reason it's disabled by default. they're up to smb 3.0, I think. the ps3 and the 360 also use smb 1.0 to map them as a network drive, so it no longer works without it enabled. you can map them as a network folder though, so it will be like dev_hdd0/packages , dev_hdd0/PS3ISO , etc as separate drives connected, but I don't think the 3DS can even do that, and even if it could, it would be a mess not to have access to the whole sd card, just folders in it. it won't be the whole drive.
