Due to bugs in the operating system, MOST games bypass most of the operating system and bang on the AGA registers directly. In order to get those game to work on a VGA monitor you must buy a scan-doubler. A scan-doubler is a hardware device that receives the image at 15KHz and outputs the same image twice at twice the horizontal sync. If you get a scan-doubler with a deinterlacer you'll not only be able to play games but also hardware-banging productivity software as well.
