<p> FindCode helps to create "bin_map" and "bin_names" files used by
<a href="../fdisasm/index.html">FDisasm</a>. </p>
<p> To use FindCode, place it in the same folder as a file
named "bin" that you are trying to disassemble. Launch
FindCode and you will see a simple text editing
window. Type a location within the "bin" file that
you believe contains code, in hexadecimal notation.
For example, "2A" (without the quotes),
for an offset of 42 (decimal) from the beginning
of "bin". Then choose the "Go" command from the
"File" menu. </p>
<p> Assuming there is code at offset 42, FindCode will
find every instruction that it thinks can definitely
be reached from there, and add this to the file
"bin_map". (The file is created if it doesn't already
exist.) It will also create labels for the
targets of branches and other memory accesses within
"bin" that it can identify, and add them to the
file "bin_names". (This file also is created if it
doesn't already exist.) It will not change
labels that already exist in "bin_names". </p>
<p> If FindCode thinks that an invalid instruction
can definitely be reached from the starting
offset you specified, it will give an error message
and make no changes to "bin_map" and "bin_names". </p>
<p> When FindCode is done, it will automatically
launch FDisasm if it is located in the same
folder. You can then enter other locations
into FindCode and choose the "Go" command.
FindCode will open and close the "bin_map"
and "bin_names" files every time the "Go"
command is chosen, so you can manually edit
these files and still leave FindCode running. </p>
<p> You can specify more than one starting offset,
separated by spaces or returns. </p>
