I've got this file called 2309osos.fw . I need to disassemble it but when i try to the dissasembler gives me a "this is not a valid win32 application" error. So i opened it with notepad and read the first couple of lines which read "If you wish to dissasemble this file for reverse-engineering purposes please chop off the first 512bytes before loading it into your dissasembler".
Question: how do i "chop off" the first 512bytes? this question may be stupid i don't know, im fairly new to this.
