Nope, it doesn't work for me.
Ver. 9.4.0-21U
This is what I did:
1.- Put both code.bin and pokemon.ekx in the SD card root.
2.- Put card back in 3DS
3.- Turn on console
4.- Open the game, to to the PC, open the box and close it.
5.- Go home without closing the game, go to the site
loadcode.projectpokemon.org6.- Browser crashes, resume game and go to Box 1 slot 1
7.- There's nothing there.
