The attached file Ixus_160-100a Vs Ixus_170-100a [Junk Vs Junk].jpg

Shows that the firmware dumps also contain a lot of data that is not
used for this  IXUS 170 Porting Attempt.

The attached file
Ixus_160-100a Vs Ixus_170-100a [RawHexData3 Vs RawHexData3].jpg
shows a comparison of the a small part of the firmware dumps.

IXUS 170 Porting Attempt continued...

This shows that when the Firmware Dumps are compared
by, just using the strings, that there is a very good relationship
between the Ixus 160 and the Ixus 170.

The attached files are a part of the difference between the firmware
Dumps. This can be viewed either by HEX or ALPHA orders.

The attached files show part of the 36171 strings that are very similar.   

i.e. Part of "Total" of the Unimportant Differences, or the Valid, HEX Offsets.

So, for this IXUS 170 Porting Attempt its starts out as a direct copy of the Ixus 160 xxxx.c files.

These files are then edited as shown in the post's below.

The attached files Ixus160_elph160_100a.prj
and Ixus170_100a.prj are the "Project" files
for the ARMu Disassembler I used for this
IXUS 170 Porting Attempt.

Awesome work picking this up! Might I suggest creating a code repository on Github?

At the moment this is only a Blind "IXUS 170 Partial Porting Attempt"
and is only about 50% completed with about 200+ diffrences from
the Ixus 160 port, there is probably about another 500+ or to find.

There a ARMu Ixus 170 project file in Reply #15 is also available.
