Using firmware from ixus850_sd800_100e_beta_2-sources.zip on my IXUS 850 IS,
works fine regarding raw & scripts (as well as zebra, histogram...)
But no overwritten features available (overwriting exposure for instance, replacing the ixus default values with the chdk ones, to go over 15sec...) - or did I misuse the piece of software ?
Anyway, great work, time-lapse and HDR finally possible thanks to scripting :-)
