It's been over a year since Phaser 2D v3 has been dead, so I thought I'd make a small guide on how to crack the editor now that it's out of support.
Cracking the editor is very easy to do, and is very low effort. To begin, start by downloading a copy of the Phaser Editor from Archive.org or similar along with Phaser Core.
Then, download a copy or Telerik Fiddler Classic
Open fiddler, and unzip phaser core.
