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.
bundle exec ./copydatrom.rb datfile.dat rom-source-dir rom-dest-dir
CopyDATROM will then:
- parse
datfile.dat - check that
rom-dest-direxists (and try to create it if not) - recursively go through every file in
rom-source-dirand:- calculate its SHA1 hash
- check for a matching SHA1 hash in
datfile.dat - copy it to
rom-dest-dirwith the corresponding ROM name specified indatfile.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.
