.SH DESCRIPTION
|
|
\fBromcmp\fP is a tool developed to detect the most common errors that
|
|
can occur when dumping ROMS, for example stuck bits and address line errors.
|
|
.PP
|
|
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.

.SH EXAMPLES
|
|
.B 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.
