A [Sega Genesis] ROM checksum corrector.
## Prerequisites

ROM in-place or supply `-s` or `--suffix` to change the default appended suffix
to something else.
```console
usage: [python] sgcc.py [-h] [-i] [-s SUFFIX] path
Compares and corrects the checksum for a Sega Genesis ROM.
positional arguments:
path Relative path to the Sega Genesis ROM file.
optional arguments:
-h, --help show this help message and exit
-i, --in-place Make header change in-place, otherwise make another file
