Is there a way that you can add a feature where you can slow your processor down to 40 mhz in the virtual? Also I have not tried it yet but maybe a usb game adapter setting so that the guest OS sees it as an older style serial adapter. defect closed VM control VirtualBox 3.2.10 wontfix Windows Windows
