I haven't tried changing it yet, but even if I can't, being able to read it will be very useful.  Now I'm trying to find the y position, and I'm trying to use the CmpProp ALT +/- action to get it to show me the changes.  But it doesn't seem to work, even when I change the x position.  It only ever shows a change at property 100, and a random one at that.  Should this feature work?

I think I tried it once or twice and it did work as instructed.
I'm pretty sure it's not working properly for me.  If I display page 19 of the params, I can see property 192 changing when I change the horizontal AF frame position (I've been switching to Play mode and back to update the params display - is there a quicker way?).  But CmpProp doesn't show any differences for it.

If I change the zoom even the tiniest bit, it shows pages and pages of changes and I have to wait quite a while before I can even turn the camera off.

Can anyone confirm they've successfully used CmpProp with an S3?  Maybe I'm doing something wrong.

I tried dumping RAM instead.  Do the resulting files include the properties?  If so, what offset do they start at?  I found too many differences to begin searching.  Can you dump just the params?
