I installed freeshop and everything needed for it, and i can download and play games and such. But after i installed all of the cia's, my o3ds won't boot up my old 2ds games. Right before the 'upgrade' pokemon black still worked, now it shows a black screen while the music of the homescreen is still playing. With other cardridges, it displays the 'an unknown error as occured'. The o3ds works fine. The o3ds is of the same country as the cardridges, so i don't think that's the problem. Can anyone help me?
