Hi there,

I did get it working.  Check out my homepage at SCEA for the game and
source code.

> "out nearly a year ago"

Damn! Has it really been that long!  Gotta get back into Yaroze coding
soon............


Regards,

I realise your original message went out nearly a year ago, but for
the benefit of anyone interested in a solution or if you never got
one here's my idea:
Use a virtual screen rather than a double buffer, and have your
two sprites (or a picture or whatever) stationary on it (positioned
at (0, 256) or wherever.  Then using two RECTs just MoveImage them
to the visual screen (using certain width settings etc).
You must set GsDefDispBuff(0, 0, 0, 0) and still do SwapDispBuff
when doing this or I found you won't see anything.  If this makes NO
sense (?) then look at the attached demo (only 3k zipped) to see
an example of a simple infinite scroller I did using this technique.
Any Q's just email me for the A.
Later,
Jim
