I downloaded pokemon black and my friend bought it.
He told me that the relocater does not work on fake pokemon game.
is this true?
and is there anything that fake games cannot do?

 

I think the relocator would work for you. relocating works on the basis of download play, that should work like any other game with that function.

you can not, however, relocate pokemon from a HG/SS you play on a flashcard, since it wouldnt access the save file of your pokemon roms.

but i dont think the cgear would work due to IR errors
cant be sure though
