The original modbin was a tool included in the 3DO SDK and is used
to modify 3DO executable's slightly custom AIF header. It was also the
name of a more advanced tool used by the 3DO Company to modify AIF
headers more extensively and in combination with RSA signing tool to
enable additional feature such as running libraries and tasks in a
privileged mode.
This tool offers all the same features found in the original modbin
tools and the RSA signing tool with a few minor extras. Should
compile with any C99 C compiler.
Usage: modbin [options]... <input-file> [<output-file>]
modbin is used to set 3DO AIF header values and sign executables.
-h --help print this help message and exit
-V print modbin version
--debug enable debugging
--nodebug disable debugging
--subsystype=UNSIGNED set folio subtype
--type=UNSIGNED set folio node type
--pri=UNSIGNED set priority
--version=UNSIGNED set version number
--flags=UNSIGNED set app flags
--osversion=UNSIGNED set OS_version number
--osrevision=UNSIGNED set OS_revision number
--stack=UNSIGNED set stack size
--freespace=UNSIGNED set freespace
--maxusecs=UNSIGNED set maximum usecs
--name=STRING executable name
--time set time
--reset resets all values to default
--sign=app|3do sign executable
To print out the current values of a 3DO AIF executable just include an input file. You can also combine that with the other options to confirm what gets set and their values. If you wish to create a new file set the output. The new file can be the same as the original if you wish to overwrite it. Be sure to re-sign if changing the values of a signed executable.

$ cd modbin
$ make
$ make release
Same as Linux's make release. Uses an Alpine container to cross compile.
