I have been looking for a real card that will play the 3D 3DS games and everywhere and everybody I ask says NO LOL

But for one guy whom just returned from Sydney and he said he just saw one that works at a market 5 days ago

Do you think this guy was just trying to scam my friend or what

And just one other thing can I upgrade a R4i v1.4 to work on a 3DS machine, i understand it wont play 3D games but could i get it to work to play the normal games

Any help would be great

Cheers
