what ds emulator is good for pokemon black and white 2?

i wanna kno what ds emulator is good for pokemon black and white 2, i'v tried desume and there was bugs that didn't allow me to check stat, or bugs that doesn't let me move forword and bug that didn't allow me to save the game.
and i've tried no$gba but the settings didn't allow me to boot up the game same as usual and i still need the cheat code for it to work so.... any emulator that works for pokemon black and white 2?
've seen this vedio on youtube and it clearly shows that he is using an emulator cuz it's showing the lower screen too
