tr_data.json - main file for translators, simple JSON file with single dictionary where key is string with Japanese text and value is string with English (currently) translation. Easy to read, edit and add new entries.
en.json - main file for KCT it's similar to the previous file but contains crc32 hash instead of Japanese strings for memory and traffic economy. Can be generated by jp2crc.py (see below).
jp2crc.py - small python script for generating crc32 hashes from Japanese strings for KCT. Usage is very simple jp2crc.py -i input_file -o output_file where imput - file like tr_data.json and output - file for KCT like en.json.
There no any dependencies, this script only uses binascii, argparse and json from standart python library.
