I was watching a video on you tube about a boy cloning pokemon through the GTS. He waited till the lil' clock made 3 n 1/2 spins... So my question is... Is it 3 1/2 spins on all modems, also, if anything goes wrong can the game data be erased?
It's different for every modem. Mine goes around 7 spins and i have to reset maybe on 7.2. Just see how long it takes you by letting the pokemon send and then take it back. Also i'm not sure about the second question. So i don't know i've cloned over 100 pokemon now and didn''t have any problems. So i would say no.
