My old SF4 Juri also suffers from the same sprite problem. Those lighting effect is kind of impossible to be disabled during the "sprite" rip process..........not to mention the color losses......
And, the size of ripped "sprites" is also very big so in MUGEN scaling something like this is needed:
xscale = 0.293 ;Horizontal scaling factor.
yscale = 0.293 ;Vertical scaling factor.
This is the scaling used by this Modern Juri.
Among all the SF4-rips, I think caraibandragonfury's is the most acceptable one........
