Instructions
Double-click on your GBA emulator icon with the left-hand button of your mouse.
Select "File" and choose "Open Cartridge." Select the GBA ROM you wish to play from your files and click the "Open" button.
Select the "Opens" button on your toolbar and choose "Frame Rate." Some GBA emulators may have this listed under "Settings."
Change the frame rate to the highest possible number it will go to. This will make your GBA emulator run much faster.
