Black and white image

Why when playing imports using composite on a modded PAL Play station, NTSC image looks gray, while playing imports in PAL SNES, in 60Hz mode, colours look fine?? Is it because I use RF output with SNES and composite with PSX??
I know PSX needs a RGB SCART cable in order to show colours. RF is not affected by this?

It's simply because the SNES 50/60Hz mod is exactly that - it switches the video output between 50Hz or 60Hz, but retains the native colour encoding. Therefore a PAL SNES will always output PAL, and an NTSC SNES will always output NTSC.

Same goes for a Dreamcast, and Gamecube.

However with the PS1 and PS2 things are slightly different - all of these machines (no matter what region) output either PAL50 or NTSC60. If you play a PAL game and choose the 60Hz option, you'll get NTSC. If you play an NTSC game on a PAL PS1, you'll get NTSC.

thanks, that's exactly what I thought
So, If I get a NTSC Famicom, the image will be gray ?? Even if I use RGB cable??

Anyway, i've seen a web about modding a PAL Mega Drive 2, and in 60Hz mode, the image looks gray too! Does it mean that Mega Drive is like PS1??

No the image will be grey if you use any other lead... If you use RGB you will get color.
And yes, if you are not using a RGB cable on your Modded Megadrive you will get a Grey image when running it in a format other than your TV's own (ie running PAL on a NTSC TV or vize versa)

But about Mega Drive gray image.. that does not happend with SNES or Master system. Why??

Thats because when you MOD a Mega Drive to output 60Hz, it switches to NTSC when your running it in 60Hz mode, so If your running it on a PAL TV, then youll get a Black and white picture because the signals are incompatible, unless you use a RGB Cable.
