. It's just this rubbish that makes these products ever more profitable.

I don't see how profitability is relevant to CHDK.

Excellent choice to remove the games! I've been following your comments in the some of the other forums as well as this one and I have considerable respect for the amount of time and effort you put into this build!

Well Done!

I am novice with digital camera/photography.

I bought a SX20is recently. Using both ACID and CameraVersion11, I obtained FW version for my camera and that is 102D. Can use your FW dump sx20-102b-0.9.9-885-full with my camera? I want to save my photographs in RAW format for future post processing. Thanks for getting rid of the Games from your FW dump. I want also my camera to be faster that what its now and I guess more free RAM will definitely do the same.

Your suggestion will be appreciated.

I think there's a bug with the newest fw build on 1.02B.. When I have the main LCD reversed (facing the same direction as the lens so I can see both), the screen is solid white and does not change unless I swivel the LCD backwards or dock it so it's like a standard camera. This also affects the viewfinder if the screen is left out that way - turns solid white, and you can't see anything you're doing, though the camera still functions normally minus the LCD view. Also, this happens in ANY mode.

I just tested mine and was able to take photos and movies as expected. Recommend you test again after starting your camera to see if it happens again. If it happens again, you might want to try adjusting one or more of the settings you changed recently. It might be a conflict of the settings or just something 'quirky' that happened.  Good luck!

I vote something quirky. Somehow, in the Misc settings in CHDK, Flashlight mode got turned on?? I don't remember messing around in the Misc menu at all ... But it's fixed, so false alarm. Sorry!

@baddogud, 102b will not work on the 102D. Dump your firmware and i'll try and port it.

Hello,  I have just obtained a dump of the SX20IS 1.02c firmware.  I would like to post the dump for any developers who are interested to work on.  Can someone let me know how/where I should upload the dump?   I have dropped it here for the time being:  http://drop.io/qad5l56/asset/primary-sx20-1-02c-bin

Re: the sx20 porting thread About "do I need a PS.FI2 file"

@Skywalker9:
Thanks alot for your precise answers about "Do I need a PS.FI2 file". Very clear. Now I understand why. Especially the part about one of the RAW bugs:

" You can import movies and JPGs and copy with Windows in a cardreader when using two partitions. After autoboot, the larger partition becomes the active partition, so USB transfers work fine normally (same as single partition). I say normally because there appears to be a 'bug' when enabling the 'place raw in same file with JPGs'. When this option is selected the contents of the folders created are not visible through USB or Windows when using two partitions (I haven't checked this on a single partition yet). If this option is enabled you cannot import via USB or view with Windows when using two partitions. Only the SDM Installer will work in this case.
Photo formats other than JPGs and movies are not recognized by USB yet (per forum comments), so they can only be done via the SDM Installer."


For the time being I have switched off the raw mode (and yes: with a two partitioned card I can now use USB for transferring images). The Superfine and battery status option are more important to me (still have to see if there is a significant difference with the standard fine setting).

However, I just installed the may 16th build of Acid2000. Testing is continued (including video mode) ....
