https://github.com/marhale3/marhale3.github.io/tree/master/_posts contains .html files for 1-516 . not sure how helpful that is, as you would need to convert the html to md.

I've been building a list of translation / app / OS projects for PE, which gives other options to source the problem list: https://gist.github.com/jayvdb/79bb3fec90741739ad9aceca1fb62c57

@jayvdb probably not totally done, right?

[jayvdb]

Yea. Not done. Github automatically did that because the PR mentioned this issue.
