I just reconnected all my systems and framemeister/lcd this weekend to clean some stuff up and noticed the N64 looked really washed out. The green grass outside the castle just looked like one solid neon green color.
Messed around with tons of settings on the framemeister and then the TV itself...finally figured out "color saturation" was really high. Turning that down to about 24/100 seemed to do the trick and suddenly all the texture of the grass came into view.
Just thought this was interesting!
