"Nintendo wifi treats game card and ds as a set" how does this work?

[cbowling816]

Just wondering if it is specific for every different copy of a game like each pokemon black counts seperately, or if all copies of black are considered the same if used in the same ds?

Mainly i need to know because i play all my games from my flash cart and i have them all backed up so i dont need to carry anything but my ds. If i connect to nintendo wifi on flash cart will i have to get a new friend code in dp/hgss everytime i back up and restore my save to and from actual game cartridge?

I transfer save between flash and retail cart when at home for pokewalker in hgss, and for gba link catching in dp on ds lite and bw b2w2 sometimes i use ir features

Thanks

the save file stores the mac address of the system when you connect to WiFi

whenever you try to connect again, it checks to see if that mac address is the current mac address. If it's not, it clears the records. No, you can't change systems because the MAC address changed.

Ok. So if i move my save between my supercard and the actual game card, nintendo wifi will see pokemon black (for example). As pokemon black regardless of whether im playing from my flash cart or retail cart? (so long as im using my ds and save file)

As long as your save file is loaded on the same DS system, you're fine.
