Finding the right values for DNG4PS

I saw a similar thread, but they were able to solve the problem by setting their camera into DNG mode.  I am playing with the experimental CHDK for the SD1200 and at best the DNG produced by the camera looks like this http://i995.photobucket.com/albums/af74/awdark1/dng.jpg

So I am trying to work with the raws from the camera.
By itself, it opens fine in Raw Therapee but it isn't photoshop.

I created a profile for DNG4ps so that it can recognize the raw files, it did and successfully outputted a few DNG files. Unfortunately they don't open in photoshop or Raw Therapee (one looks garbled the other one is purple).  However my computer has "FastPictureViewer" installed so I can view the raw files I normally work with and the preview thumnail and preview in picture and fax viewer look fine.  

Is this behavior normal or have I screwed up?

Re: Are the DNG files generated by DNG4PS supposed to open in photoshop?

I was looking at this page which specifies the values used for DNG4ps http://snafs.com/tag/dng4ps/ and I was wondering where the original values were found.  I am aware the \include\camera.h file contains the values used however I am trying to find it for a different camera and I am unsure of the values being used.

If you can pull any information from the RAW + JPG IMG_0760.zip - 15.84MB it is attached  :)

I got values which allowed DNG4PS to generate an image that can work in photoshop listed here http://chdk.setepontos.com/index.php/topic,4324.msg46735.html#msg46735
How do people normally approach retrieving the proper values?  I found it through trial and error.
