NAME

       romcmp - MAME rom and romsets check and comparison tool

SYNOPSIS

       romcmp [-option] [dir1|zip1] [dir2|zip2]

DESCRIPTION

       romcmp is a tool developed to detect the most common errors that can occur when dumping ROMS, for example
       stuck bits and address line errors.

       It can check the ROMs in ZIP files or subdirectories; it can also be used to compare  two  ROM  sets,  by
       giving it two files or subdirectories as parameters. It will determine which ROMS are identical and which
       are the closest matches.  This is useful when figuring out if a newly  dumped  ROM  set  is  a  clone  of
       another ROM set.

OPTIONS

       -d     Enables a slower, more comprehensive comparison.

EXAMPLES

       romcmp jumpkids.zip will output the following:

         11 files
         23.3c             FIXED BITS (xxxxxx1x)
         23.3c             FIRST AND SECOND HALF IDENTICAL

       This  tells  us  that the 23.3C ROM in Jump Kids is bad, and incidentally, it causes the missing sound in
       that game.
