I'd suggest buying a 3DS, Pokémon X and/or Y, an electric device with a camera and VNC capabilities, and VNC software for your computer.
Step One: Turn on your 3DS with X or Y in the game slot.
Step Two: Using an electric device with a camera and VNC capabilities, start recording your 3DS's screen.
Step Three: Activate your computer's VNC software and watch your 3DS's screen from your computer.
Basically, don't pirate :P
Also, there is no such thing as a 3DS emu.
I know how it works but it cost some damn money
And i have other things where i have 2 spend my money on.
I heard Gateaway released a 3DS Flashcard but im not sure if there even are 3ds roms
I don't think anyone has made a 3DS emulator. There'd definitely be news if someone cracked it. 3DS Roms do not exist because the 3DS itself hasn't been cracked.
