I brought a Nintendo 3DS from France, I know actual R4 cards don't play 3DS games but at least they can with DSi games.
Do you know where I can find R4 or R4 Gold for DS3 in Lebanon?
Edit: Nino has plenty of R4's (i think)

I'll try to confirm tomorrow.
Nino store in beirut malla 50m after pain Do'r on your right. :P I worked there for a few :P.
Anyway he does have r4s but as said they dont work in 3d only 3d.
