This is a small tool that allows you to replace strings in a binary file.
It is mainly useful for working with 'strange' encodings like shiftjis,
which are particularly painful to work with using a hex editor.
Find out the general range of the file which contains text and
which encoding it uses. Then execute the following.
python string-finder.py FILE START END ENCODING
So for example:
python binary.bin 0x100 0x200 shiftjis
This will create a file strings.txt which contains all the
valid strings it found in that file from offset 0x100 to 0x200.
For a list of valid encodings, click here.
The strings.txt file you created will contain stuff like
# "This is some text"
#@209096-23=
meaning that it found the string "This is some text"
at offset 209096 and the replacement text can be up to 23 bytes long.
Editing the text is done by removing the # in front of the @ and
typing the replacement after the =.
So for example
# "This is some text"
@209096-23=This is the replacement
IMPORTANT: Do NOT change anything that does not look like
valid text, it probably is not text at all and you might
be changing (and possibly corrupting) unrelated things.
When you are done, run the following to do the modifications
python string-replace.py FILE STRINGS_FILE
So for example
python string-replace.py binary.bin strings.txt
This will overwrite binary.bin, so create a backup.
