I am new to this site and actually don't know so much about m3 yet. I have a m3 perfect SD and a Diamond on it + DS lite. A friend told me that if I have say, Emerald on my m3 with a save I will be able to trade with my Diamond using only my own DS and m3. When I start Diamond, go to Pal Park when it's unlocked and try to transfer some pkmn, my Diamond should think that I have a real game in the the GBA-slot and I will be able to transfer my pkmn.
1. Do someone know how to do this?(my friend only know it's possible)
2. Does it work on my m3 or should I buy a m3 simply or other?
