I have 2 .exe files that I have disassembled with Win32DASM and I want to compare the two disassembled .exes... i.e (Compare all the ASM of both files for any differences).
Thanks.

Hello,
Save the two disassembled files as text files and take them
in something like windiff... or similar dev tool, windiff may
become quit old...
this may worth have a look, didn't tried it myself :

If they are almost identical apart from a few opcodes, then use the dos utility FC.
Eg.
FC asm1.asm asm2.asm > diff.asm
diff.asm will now contain the differences.
FC is provided with Windows and can do both text and binary files.

Note that FC will not work if there is a small difference in linking offset, eg. the same routines are placed at location+offset in the second file. Then FC will show a lot of differences for same code. Text compare of disassember output files is a bit better but still a lot of work.

I think you need to use HWorks (hex workshop 3) to find the dif bytes (to patch) between your 'unpacked-target.exe' and the 'ready-cracked-unpacked-target.exe'.........
Just <right-click> on exe's and 'compare'. That gives you the offset
that it ?
