Cooming 2013: "Yumiko in the haunted Mansion"

Not a bad idea after all. This would save a lot of memory, especialy if the graphics is compressed.

Yes - this method is pretty simple. On the plus side it doesn't mask out holes in the sprite. On the downside, if it can't be "filled" from the side, it will be imperfect.

You could do a whole fill routine, I suppose, to build a mask. Or mask all 0 bits anyway, and have the eyes see through?
