From the developer:
HEX Editor Pro ? is a hexadecimal editor, an editor used to edit such files, which you cannot normally edit with regular text editors. Thus, it can be used for software debugging, cheating in games, editing files, containing non-text symbols, etc. It can edit any small (up to 500K) file in three different modes: hexadecimal (HEX), binary (BIN), and text. In binary mode, it is possible to edit separate bits.
