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.
