Other tricks you can do are: Spin the Wings A+B connector block around 180 degrees, and you should have access to everything but the LEDs and slide switches, plus 16 pins of I/O.
Plug the WIng B pins into the WingC socket and have VGA, Joystick, audio and 32 pins of I/O.
Of course you have to update your UCF files. Here is my updated UCF file for using the Switches and LEDs - Please note I number my LEDs wth LED0 on the right and LED7 on the left - the opposite way to the silk screening! # LogicStart Megawing with Wing C only plugged into the Wing B socket NET switches(7) LOC = "P85" ; NET switches(6) LOC = "P83" ; NET switches(5) LOC = "P78" ; NET switches(4) LOC = "P71" ; NET switches(3) LOC = "P68" ; NET switches(2) LOC = "P66" ; NET switches(1) LOC = "P63" ; NET switches(0) LOC = "P61" ; NET LEDs(7) LOC = "P58" ; NET LEDs(6) LOC = "P54" ; NET LEDs(5) LOC = "P41" ; NET LEDs(4) LOC = "P36" ; NET LEDs(3) LOC = "P34" ; NET LEDs(2) LOC = "P32" ; NET LEDs(1) LOC = "P25" ; NET LEDs(0) LOC = "P22" ;
