How to Make a HEX File
A hex file is a hexadecimal representation of a document. Binary files require hex editing programs to modify their program data. These hexadecimal representations correspond to instructions in the code, and having a map of it allows you to debug and modify a program or memory dump. Making hex files can be done through the use of editing programs that are found free online.
