=== Checksums ===
See below for [[#checksum information|checksum information]].
 
FCS32 and SHA1 are given here as these are what MESS uses.  FCS32 in this instance refers to the 32-bit CRC standardised as ISO 3309, ISO/IEC 13239:2002 and ITU-T V.42, most notably used as the Ethernet Frame Check Sequence (FCS), which has a polynomial representation of 0x04C11DB7 in normal form.  It is also used for zip and gzip  files, and within UDI disk images.
 
On Unix-like systems, Jacksum will produce an FCS32 sum when using:
 
jacksum -x -a fcs32 FILES
 
and rhash will do so when using:
 
rhash --lowercase -C FILES
 
To produce a line similar to that needed for this article, with minimal editing, one can use:
 
jacksum -a crc32+sha1+md5 -F "|#FILENAME||#FILESIZE||#CHECKSUM{0}||#CHECKSUM{1}||#CHECKSUM{2}" FILES
 
or:
 
rhash -p "|%20f||%s||%c||%h||%m\n" FILES
 
Note that checksums can be freely shared on the Internet without concern over copyright, as these simply provide a mechanism for determining validity of ROM dumps that you already have.
