Is the modified udumper working on the SD780?  I'd like to try it on my 1.00B camera.

Never tried.  But you can try it and tell us.  :)

I tried the diskboot.bin from http://chdk.setepontos.com/index.php/topic,4095.msg39924.html#msg39924 and couldn't get anything.

I'm not sure how universal these modified udumpers are, or how easily they can be adapted to different cameras.

We've figured out the diskboot code, but the udumper code itself probably needs adjustment.

whatever changes worked in this thread http://chdk.setepontos.com/index.php/topic,4310.15.html may be applicable.
Don't forget what the H stands for.

@reyalp - heads up
New palette seems to be required for the SD780 - I've matched the colors somewhat to name but any suggestions other then "seem to pick the right #"?

Also note that SCREEN_COLOR from the gui_bench.c will need to be moved because 0xF7 is white for me.  :(

Not really. If you (or one of the other testers) has another CHDK camera, you can try to find the best match by comparing them side by side. Really it doesn't matter much as long as all the displays are legible.

Everything that uses hard coded color constants should be centralized in the palette ifdefs.  Note that SCREEN_COLOR is defined separately in multiple files, and the games have several other hard coded defines  ;)

I apparently missed a bunch of stuff when I did the SD990

I guess your guess is wrong...  ;)

They have about 2 megapixels, compared to 8 megapixels in the jpeg files. I do not think it's a probem of "Raw Photo Processor",
Many viewers / image processing tools shows either 1/2 the image or only a small thumbnail of RAW files by default due to performance/faster response...e.g. in XNView: "Camera RAW: half size / full size / thumbnail only"

--> There's also such a setting for RAW images in Irfanview !

Do we gain any more details with RAW images besides uncompressed images (e.g. more bit depth and so on)?
