Some of software versions might not be supported by this tool even though hardware codes are same. If you want to add support for some specific ROM, you can make a pull request or create a new issue ticket with hardware and software (chip) codes and link to original firmware/ROM. The tool will not try to calculate checksum if it can't recognise firmware/ROM.

Usage:

1. Build tool

   make build
   make build-windows
   make build-linux
   

2. Use it to correct checksums. It will ask for input file. File can be dragged into command window. Tool will overwrite input file.
