we wanted to use the Alpha Star matches to create new visualizations to compare how a human plays and how the AI plays.

We started out figuring out how sc2reader works by using a random ladder game.

I later found out that only standard ladder games seem to be fully supported.

I am quite competent in python, and with a high level overview of what is required to get sc2reader to open the alpha star matches, I would be willing to undertake the work and make our visualization project available for the community.

I really hope I can get some help with this otherwise we will have to take regular replays and it won't be as interesting.

Kind regards

Hi Philippe,

that would be great if you could improve sc2reader for this!

My understanding is that AlphaStar ran on a custom version of SC2 that is used by the bots. I'm not sure how it works, but maybe the SC2AI community has a better idea.

The closest thing we have run into like this is that Blizzard's dataset of replays for training AIs was anonymized, so it was missing a bunch of data that we assumed would be present. You can see the discussion and effort on these tasks at

You're definitely welcome to submit a Pull Request if you figure it out. We'll do our best to answer any questions that you have about it as well. I suggest that you open a new issue on GitHub rather than continuing the discussion here since I think the (small) sc2reader developer community is more active there.
