I noticed that the games which are RGB Patched such as Street Fighter Alpha 3 (kal-sfa3) and others have a poorer picture quality than the PAL versions which already have true RGB support.

In Street Fighter Alpha 3 (kal-sfa3) with the RGB patch applied, the picture has faint lines going across from top to bottom which are quite faint but can easily be seen.

Also I compared Last Blade 2 US & JAP versions and the JAP version also has this problem but the US version does not.

Is there any way to remove this distortion?

I'm using a NTSC/U Dreamcast with a RGB Scart Cable on a 50Hz/60Hz TV. The same problem also occurs on a PAL & JAP Dreamcast at my friends house on his TV.
