From what I've heard you need an emulator such as Visual boy advance(vba). Once you have it, right click on the gba file and go to open with. Then choose Visual Boy Advance. Then click apply. Then double click the gba file and there you go. But when I do it, it says that it is not a valid win32 application. If this happens to you then open Visual Boy Advance, then go to open. Then choose the gba file. THEN it should work. If it lags, then your computer is either slow or has little to no memory.

There actually is no virtual boy advance. I think you may be thinking of Visual Boy Advance which is the same thing as the Game Boy Advance
