Does nobody really know what's going on? I've searched everywhere and only found people who can't get the NDS emulator to work in RetroArch, but there's never a solution in the answers.

When I import any Nintendo DS game, RetroArch it doesn't open. I tried delete RetroArch from Emulators folder and download it cleanly, but everything remains the same. Do you know why this is happening? Do I need to do something else besides importing the game?
