Does anyone know of a hex editor which I can use to narrow down the location of a variable or something? Like I know the value at instance 1, and then in instance 2 it will change in the file (a custom format I made it's binary written so it should work no?) .. anyways I want to find all the values that change from instance 1 to instance 2 in the file so that I can narrow down the location and see if I can change it, effectively hacking/cracking my program.
