Here’s a list of all the helpful tools we all use when hexing. The two major programs are Petz Workshop and Lnz Pro side by side. It’s best to learn the actual way of hexing (working with hexadecimals, the number’s side), so you can better understand when the times comes to integrate Lnz Pro with Petz Workshop, your life would be a lot easier. Even though Lnz Pro and Petz Workshop, are the primary hexing utility of today’s PC, people still use Resource Hacker (Or “ResHacker”) to hex. Another popular hexing program of the past, was Hex Workshop.
You can really chose what program you’d like to use, it really all is personal preference, but a lot will tell you that Petz Workshop together with Lnz Pro is the best method of hexing.
