This git repository is meant to be pushed to the heroku SAS platform. If you're not familiar with heroku, work through their tutorial before trying to use this. It's based on the Flask framework. You'll want to get familiar with that as well.
You can push it as is to verify that it will correctly serve the file & repository on it. Open / to get the list of files in the repository. Check that you can download the arduboy file (a zip file) and the ardumate version of the repo (a json file). If that works, you should be set.
Update the static directory to include your hex files, screenshots
and banner images. Make sure to update git to match. Then edit
games.py to describe your repository and the games you've just
installed. Commit that, then push it to heroku to launch it.
The html version of a repo page is probably better done as a template, but I'd rather write code than a template, so you get code. If someone wants to submit a PR with a version that uses templates and modern HTML, I'd probably merge that.
The arduboy output for 1010 crashes Arduboy manager, but works in Arduboy game loader. This is still being investigated.
