Perfect! Thanks alot! 

And if I wanna play other consoles, they will never end on .exe? They will also end on .(whatever console the game is)?

Oh Thank you for the warning.
Where do you usually download the ROMS from? I am such a noob. So Sorry.

Yes I did that. I downloaded the Cores in RetroArch, that I need. And it starts a Window but the game won`t start. It is just a white screen.

These are my settings for example.

Good Sunday from Switzerland everyone!

I am basically new to the world of emulators and LaunchBox and whatelse there is out there.
But a friend of mine had Ninendo games on his computer, what triggered me to try it myself this weekend.
So I ended up downloading RetroArch and Launchbox this morning. I followed the steps of a Youtube tutorial.
The next step was to download some games. I just went on Romsmania.cc and got the first game they recommended just to try it out. 
I downloaded and imported the game. Everything seemed to work. 
Now there is just one huge problem: The game won`t start. And I have no clue where I went wrong or which settings aren`t the right ones.
Is there any one or any thing that could help me?
