Not a problem but I thought of this because of the threads about the motherboards "unknown" ports.

I remember that within a few games some sound effects triggered a kind of sound filter that decreased the light from the power led (1200 and 600, I don't know for 500).

In Dune (french version) there was a key toggling between the filtered and non-filtered sound.

And in Lotus II, during the second race, when driving under a tunnel this "filtering" system was used to provide an echo/enveloppe effect.

I can't find the key for Dune anymore, but I checked, the effect is emulated in Lotus II.

Anybody knowing more about the reasons of the LED change ? And what was the purpose of this filter ?

And will the LED change be one day emulated :-p?

The toggle key in Dune is F3, but you have to press another key (any key) between each press, otherwise it won't do anything.
