This is a specially modified version of Image-ExifTool that allows to make byte exact copies of the Minolta Dimage A1 camera original from a copy edited by exiftool >= 7.34.

If you set environment variable MINOLTA_BYTE_EXACT=4 and then remove all tags you added, you will get a copy, that is equal to the original file as it came from the camera.

ExifTool is a customisable set of Perl modules plus a full-featured application for reading and writing meta information in a wide variety of files, including the maker note information of many digital cameras by various manufacturers such as Canon, Casio, FujiFilm, GE, HP, JVC/Victor, Kodak, Leaf, Minolta/Konica-Minolta, Nikon, Olympus/Epson, Panasonic/Leica, Pentax/Asahi, Reconyx, Ricoh, Samsung, Sanyo, Sigma/Foveon and Sony.
