Alright thanks, I''ll try this.

As far as I remember yes,but how can this affect my problem?What if I don't save them in the SD card?

Thanks for answering.Every game that I have already tried was extracted and was .nds . Somehow after downloading a lot of games a Pokémon heart gold version got to be the right and I'm playing that game for the moment but nothing else rather than that.

Everytime I open any game the screen is white I can see the buttons but there is also no sound.I have tried changing some settings following some videos on youtube but I still can't fix it.Any solutions?Here is what I see on my screen: https://imgur.com/snZzkde
