sync of sprites and shadows in xmen #806

Closed rp-jt closed 1 week ago

rp-jt commented 1 week ago

This fixes shadow and object not being synced in xmen. Also, negating the shadow value that goes in the colmix fixes the colour of the images making shd_in. However, this makes shadow_in active low entering jtcolmix_053251 whereas measured in the pcb it appeared to be active high. Maybe the signal should be negated after entering this module and not before?

Before changes: frame_00002

I think we measured the Sunset Riders board. Maybe the input signal to the 053251 is negated on the X-Men board. We should check that PCB.

Thanks @jotego . I will check it in the PCB later :+1:
