NO GBA EMULATOR/NDS EMULATOR FOR PC

*This article is all about the problems many users experiences when it comes to playing nds games on their computer through an emulation.
-Just follow what you see in this image then everything will work out fine. By the way you can access it by pressing F11 on your keyboard.
-If you are playing pokemon pearl, diamond, or platinum. Just press X on your keyboard so that the menu will appear.
There's no start button on NDS so the button assigned for the start will not work.
