Yes, you are correct. This means your cable has a RGB to composite circuit
builtin? That is not a trivial circuit but requires at least one special IC,
some crystal oscillators and coils.
The rolling is the 50 HZ - 60 Hz problem.

Subject: RE: SCART to composite
I already have a cable that plugs into the SCART port on the MSX2, and on
the composite plugs on the television. This outputs an RGB signal, and,
since RGB is the same for either PAL or NTSC, I should be getting the image,
displaying in proper colours, correct? (It would still be rolling until I
use vdp(10)=0, of course.)

Without additional hardware (composite PAL to NTSC converter) I think it is
not possible to use the composite PAL output to drive a NTSC monitor. Your
garbled screen explains this, because the PAL signal contains color
information that drives your NTSC monitor nuts.
With the VDP comamnd you effectively switch off the color info and the
signal contains only intensity.
You could have better luck with a monitor with an RGB connector. That way
you avoid the PAL color manipulation. And RGB is so much sharper.

Just recently, I finally got my MSX2 in the mail. However, I've been having
a good deal of problems with it.
First of all, the SCART-to-composite connector outputs pure garbage, with
some strange glitch rolling from top to bottom. The cable supposedly
converts the SCART output to composite, and the audio is fine, oddly enough.
Secondly, even when I use the "vdp(10)=vdp(10) AND 253 ' 253=11111101" or
"vdp(10)=0" commands, the image displays in black and white. This is due to
the differences between PAL and NTSC, correct?
Finally, my MSX2 suddenly started complaining "Disk offline" and suddenly
refused to read floppies. I think that it is no longer capable of detecting
floppies, perhaps because of a worn-out rubber band, as was suggested to me.
Is this correct?
