The main problem is in the fact that I also don't have HW2 calc
to test. But, what is curious to me is the fact that my routine
is practically the same as used in Universal OS, but everyone
says that UniOS gives much better results... I don't know what
is the main reason of flickers, because I can not accept the
argumentations that some size improvements which takes only few
T states may cause such ugly flickers... I am open to any
constructive dialogs about critical points in grayscale routine.
If you can send to me any flickerless grayscale which is not
extremely size-wasting (i.e. with completely unrolled loops),
please send it to me. I will be very happy.
Cheers,
Zeljko
