I believe this conversion may depend on which model Rolleidoscop is in
question.

120 film goes straight into any Rolliedoscop, I believe. The frame counting
is the problem.

The film numbering on 120 film is not set up the same as the numbering on
the original film intended for the Rolleidoscop. I seem to recall that the
rectangular window on my Rolleidoscop is in such a position that it only
"sees" the 6x9 image counter markings on modern 120 film. This is a pest, as
if the window was in a different spot, one could see the 6x6 markings, and
just use every second one. 

As I have the long-rectanglar-window version, all I have to do is place a
new label over the counter window-flap. This label is attached below. The
user winds the 6x6 frame numbers to the arrows show. The first one is a
doozy, as you can't see "1" coming up.

A friend has another version of the Rolleidoscop with two small, round
counter windows in the back. To convert his camera, a previous owner fitted
a third round window, at a different height so it sees the twelve 6x6
markings. Then you only use the "odd" frame numbers.

Also attached, FYI, is my drawing that helped me determine how 120 film
should progress through a Rolleidoscop.

Hope this helps.
I haven't posted to the list for ages.
