Should use that leak of GitHub source code from some years back to fire up an `.ru`-based clone at this point. These people are clowns.
You're talking about gitflic.ru
Why would one need Github source code to clone what git does, even if there were not already several dozen off-the-shelf self-host solutions (Gitlab says hi)?
You don't even need github source code. You could spin up a gitlab community server (or Forgejo or 50 other options) today to host these projects, but your domain/server provider will shut you down in two hours.
And if that doesn't happen, wait till you find a legal letter sent from Nintendo lawyers in your mailbox.
Unless you want to play hide and seek like z library or pirate bay which will become a full time job.
