Yes.

The main issue here is the colour encoding. If you could get a usable display
from your Atari in 50Hz mode, you will get a usable display from the Famicom.

If your VGA/TV converter only understands NTSC colour encoding, the picture
will be in black-and-white. (Assuming that it works with a 50Hz/625 line
picture.)

You can get analogue NTSC-to-PAL colour standard converters, which only change
the colour encoding, not the number of lines per field, for about US$80 if I
remember rightly; I believe MCM Electronics sell something like that. Short of
making/buying a PAL-to-RGB decoder, that is what you want and would give
better results more expensive standards converters.


Depending on exactly which console you have, it may be possible to modify it
to give true NTSC output; some Famicom clone consoles have this capability,
but a real one does not.

Oh, if your Famicom only has RF output, you'll need a TV tuner that is
compatible with its signal.


[Contact me by email if you need more help, and give a description of the
console.]
