Tried searching for a utility like this, but couldn't find any.
Attached is a simple command line utility that takes a CHDK configuration file and converts it to text.
Usage: conf2txt <input file> <output file>
Config values with size of 1..4 bytes will be treated as integer, longer values will be handled as text. The resulting file will contain lines like<ID> = <value as decimal> (<value as hex>)
<ID> = "string"
I created this to make comparing configurations easier (I had a corrupted conf file on one of my cameras).
C source (not too nice) and Win32 binary
