Hi,
I created a custom run-time image file, but its not executing in the
emulator. The emulator window appears but the screen is always black.

I am executing the following statement from command line -

start "" "C:\Program Files\Windows CE
Tools\Common\Platman\bin\Emulator_500.exe" /CEImage
"C:\WINCE500\PBWorkspaces\myworkspace\RelDir\Emulator_x86_Debug\NK.bin"
/ethernet virtualswitch /MemorySize 48

There is no change even when i use a skin.

Please help.
