Whenever I try to run ds games for example pokemon white or some 3ds games for example pokemon ultra moon, a black screen stays there when I try to open it. I have to shut it down for it to exit, as no buttons do anything. Was wondering how to fix, bought 3ds already modded so I don’t know if the person who did it just did something wrong. It is homebrewed. Already have tried deleting and redownloading the games. Appreciate any help, thanks
