Shadebobs wth STE blitter?
Posted by: defjam Mar,28.2016-21:10 

I'm curious if shadebobs can be done with the STE blitter, or even have been done.

My guess is, it's not possible because of the data-dependencies,
the layout for shadebobs is this:

Plane[X]' = Plane[X] xor DataIn
DataIn' = Plane[X] and DataIn

X 0...3
DataIn is initialised with the 1bpp 16 pix spritedata.
The function is iterative starting with plane0(X=0) till plane3(X=3)


Any ideas?
