WinHex

You can parse various files to view information and change HEX data. Works with various types of files and disks. This file cannot be printed, so I had to look it up in a hex editor. More than that, however, the hex editor can be used to create additional in-game mods that can fit into that small save file space. You can use it to edit various forms of program files and resources. You can specify the files you want to scan, but you will have to wait until the scan is complete before you can see the files. It allows you to manipulate executable files and several other types of files. Unlike many similar solutions, it is not limited to just binaries. Hex editing of files should not be necessary all the time. It supports drives formatted as FAT, NTFS, Ext2/3. Detailed documentation is provided to help you get started. It comes under the IDE/file editor category and is licensed as shareware for 32-bit and 64-bit Windows platforms and can be used as a free trial until the trial period ends. A demo version of WinHex is available as a free download to all users of the software, with potential limitations compared to the full version.

After you get the 3,3 MB (winhex.zip) installation file double click on .exe file.

Then follow the setup steps.
