Known Bugs:
Green Screen over RGB-Cable on XBox version 1.6 (will be fixed soon)
At the main menue some third-party joypads (Big Ben etc.) won?t work, please
use the original M$ pad and make sure its sticking in the joyport before you
power on your box.
If you want to use network flash, make sure DHCP in your network is activated,
or you will have to wait some seconds before you get the IP-Adress.
