It says on the PE2K rules that discussion of ROMs and emulators is prohibited. "5. No illegal material allowed (Roms, Emulators, copyrighted materials, etc.)" under Post #1: Rules, Signing Up.
I am discussing about the fact that Pokemon Black and White can be played in DS as well as in 3DS.
The fact that you mentioned emulators in your first post started this whole thing. Next time, don't even mention them. Just ask you question and do no bring them up.
