I have added QEMU to the latest build. To test your bootable USB drive, simply select the USB drive you want to boot from and press F11. You can make a virtual hard disk of any size and set the amount of RAM memory to make available to the emulation session. This allows you to test USB drives which can install DOS or XP OS's. Note however that QEMU is not very fast and that OS installs do not always boot.
