Can i use the same *.cfg file on several sdcards and for several different camera models?
A. Since mid-september 08 you can use any cchdk.cfg on any Versions of CHDK, including upcoming releases * – if not we will make an announcement or probably just rename the config file. You can use the same cfg on several sdcards without a problem – however you should NOT use a cfg from another camera model, i.e. a cfg from a G9 in an ixus – they are probably not compatible to each other. Also note that if you copy the whole content of an SD card to another sdcard in order to use it on another camera (be it another model (i.e. g9 vs. ixus) or the same model) some things might not work so well, for example the badpixel file – it differs from camera to camera. Also the *.edg files will at least differ from different models.
