Powershot SD 990 IS

Hello everyone,

As excited as I was when I heard about having a prior version of Powershot, I got someone upset when I bought this 990 IS and read after there is no CHDK out for it yet. I was hoping I missed a post or the CHDK release? Is their one for the 990 IS? with partial features perhaps? Any info would be great....

Thanks in advance guys!

There is not even a ROM dump or page on the wiki for this camera yet AFAIK.

now i'm even more convinced I should start considering returning it... the idea of this firmware is just way too enticing.   :blink:

You should at least try to get a dump before you return it. See Porting the CHDK - CHDK Wiki
and
[HOW TO] How to Dump Firmware ?

Good Point. I read up some and the first question says "What are the necessary steps to port the CHDK firmware on a DIGIC II/III cam which is currently not supported?". This is a DIGIC IV proc. Are there any side effects to the camera?  :blink:

If not, I can go ahead and give that a shot and put it out there.

Several digic IV cams have been successfully dumped using cardtricks/udumper with the "new dryos" method.

It's very unlikely that udumper could damage the camera (the worst that is likely to happen is you have to take the battery out or reformat your sd card) but obviously running non-standard software is at your own risk.

It is one of the pieces needed for a port to happen. However, the other, much larger piece is still missing: A developer with the motivation, time and skill to complete the port ;)
