Ogaiago can import .osr scores and replays in your ripple database, or simply remove the header of an .osr file to get a server-like replay. It's up to you.
Make sure you have Python 3 and pymysql installed.
Make a folder called replays in the same directory as ogaiago.py and place your .osr files exported from osu! in that folder.
Optional: If you want to import the scores inside a ripple db and rename the server scores atomatically, rename config.sample.ini to config.ini and configure it with your ripple db credentials.
Then, run
$ python3 ogaiago.py
and magic will happend. For more options and arguments, run
$ python3 ogaiago.py --help
That's it! You're well on your way to become an ogaiago na emoceb ot yaw ruoy no llew er'uoY !ti s'tahT
