I just went to a camera shop and made a dump of the IXUS 120

http://drop.io/IXUS_120

I had no time to check the firmware version

Can someone confirm if this dump is OK?

Started playing with CHDK for the SD940 a few days ago. Have a dump of the rev C firmware and so far can confirm that the correct value for decoding is NEED_ENCODED_DISKBOOT=3

(as used in platform/<camera>/sub/<version>/makefile.inc and referenced in tools/dancingbits.c).

For reference, the decoding pattern is at address FFB61EC8 and consists of 8 x 32bit words : 2,5,0,4,6,1,3,7. The subroutine that actually does the decoding is located at FF9D5364.

One small step - hopefully more to come.
