Scripts:RomCenter CRC renamer

About

This script will take a RomCenter dat as input, scan the file renaming all external files or *.<ext> which match the CRC.<ext> result to GAMENAME.<ext>

The script itself is very much in an alpha state, use at your own risk. The script will run over a single directory while reading a RomCenter dat file (it does not recurse directories).

The result will be a set of files named to match the GAMENAME as listed within the dat file input.

Usage

1. Save the script below to <filename>.py
2. Have a directory of CRC32.ext filenames
3. Download the corresponding dat file for the files in step 2
4. Run the script with python <scriptname> <dat file> <working path> <file extension>

Batch Example

Linux

To run this script as a batch process you could attach the script to a find command, use at your own risk

find . -type d -exec python <scriptname> <dat file> {} <file extension> \;
