"BinPatch.exe" is a versatile file reading and patching program. Using it, you can inspect and modify the contents of any file, extract segments from the file, and splice files together. The primary display is in hexadecimal format, with an ASCII display as well. Not all ASCII byte values have printable characters. For most of these, other characters have been substituted in the ASCII display column.
File contents are displayed in much the same format as the old DOS "View" program.
Download BinPatchHlp.txt to the same directory as BinPatch.exe so that the full instructions will be available.
WARNING: I am cautiously sending you "BinPatch". I hope possible
users make backup copies of files before trying to patch them, as I will take no
responsibility if they corrupt a file.
