CopyDATROM

This is designed to be an incredibly simple ROM "renaming" (actually just copying while renaming) utility for use with DAT files. The other tools I found for dealing with DAT files and ROM management/renaming/organization were more confusing to me than just giving up and writing this.

Usage

bundle exec ./copydatrom.rb datfile.dat rom-source-dir rom-dest-dir

CopyDATROM will then:

  • parse datfile.dat
  • check that rom-dest-dir exists (and try to create it if not)
  • recursively go through every file in rom-source-dir and:
    • calculate its SHA1 hash
    • check for a matching SHA1 hash in datfile.dat
    • copy it to rom-dest-dir with the corresponding ROM name specified in datfile.dat, if a match is found

That's it! All your files in rom-source-dir should remain completely untouched.

CopyDATROM will not:

  • modify or delete your source files
  • go inside zip/7z/rar files
  • generate zip/7z/rar files
  • generate split/merged/non-merged sets
  • generate statistics about how many ROMs you have or are missing
  • calculate CRC32/MD5 hashes (your DAT file must have SHA1 hashes)

Pull requests for some of these may be accepted, if they can maintain the tool's simplicity-of-use.

If you want to make a "1G1R" (one game, one ROM) romset from a romset with many possible duplicates and disorganized naming (i.e. GoodTools/GoodSets romsets), you can use CopyDATROM with no-intro DAT files to first rename/copy your ROMs into no-intro's naming, then use the 1g1r-romset-generator on the renamed directory.
