Simultaneous Emulators??

Prolly going to sound like a stupid question so forgive me if it is.
Is it possible to join two emulators together that are running simultaneously.
Some games have features on them that require Console links via WIFI. I know emulators can't do it that way, is there a way that they can?Any help.
Thanks.

Another question. The old versions of the no$gba emulator had a speed buttom on it. Whereas it sped up the game speed at the press of a button.
Is there an add on for the new version where this is possible??

There are multi-purpose emulators, but not simulataneous ones. The concept may be possibly on computer, but on consoles or fixed CPU it is near impossible unless they are quite powerful.

there is a version of VBA that allows this for GBA roms (and probably older GB roms), but no NDS emulator can do it at this time.
