If anyone can help, I'm having the same issue. I'm using a knockoff r4 gold pro card. I tried to get YS menu from (https://www.reddit.com/r/3dshacks/comments/48oju8/ys_menu_on_r4isdhccom_cards_as_primary_kernel/) from this link someone posted (https://www.dropbox.com/s/3xxj84uplr97z1k/R4.dat?dl=0) and it sorta loaded, but has a bunch of errors and still couldn't run the Arceus distribution.
