Hexedit Software (Free)

Review by Peter: It's a really good program. You can do all the things you want to do, insert blocks, insert/delete single bytes etc. Things you kind of take for granted these days (that is, if you're an old school 80s ml-coder) but in fact is hard to find (strangely!) in modern freeware/shareware software when it comes to raw hex editing. I didn't find any downsides with this software. I recommend it heartily! (5/5 - 5-Sep-2005)
