The custom scart cable is not well shielded, he'll make one for me with better shielding as well, with the audio pins attached.

But indeed, what comes to the component adapter, it's quite strange as the picture is bit darker, have ghosting a bit as well the colors have stripes.

Both run at 60hz mode from IIGS.

The quide for the custom scart-cable:
