kingdom hearts re:coded tag mode question

[treos]

i'm playing the game on desmume and read on gamefaqs.com that you can leave it in tag mode and eventually meet randomly generated artificial avatars.

my question is will this work on a emulator? seems about as likely as me finding a point to such a emulator even having wireless functions like that which is unlikely

i kinda doubt this would work actually

edit: got my answer just now and it does indeed work on a emulator, just leave the thing sitting in tag mode and a randomly generated avatar will appear... eventually (this is anything but fast, even while holding desmume's fast foward button)
