ENABLE_CONSTANT_ALPHA:
Sprite D Sprite constant alpha provides a way to apply
an alpha value to all video sprite pixels. Each pixel color channel is multiplied by the
constant alpha before proceeding to the blender. This can be used to create fade out
effects. This is intended for CE device use where the video sprite might still be used to
generate video output.
0 Sprite D Constant Alpha is disabled

This field provides the alpha value when
constant alpha is enabled. A value of FF means fully opaque and a value of zero means
fully transparent. Values in between those values allow for a blending of sprite with
other surfaces.
