GMS2 Version Faking

Hello in this post I will show you how to "spoof" the GMS2 version with Fiddler. The reason you would want to do this is to not have to update and to not be bugged about updates. Please note that I am using v2.1.4.285 and the latest is v2.1.4.295 at the time of this post and I am using Windows 10. Let's begin!


  1. Download and install Telerik Fiddler
  2. Open up Fiddler and wait for it to load, after that open GMS2
  3. In fiddler enable HTTPS decrypting
  4. You should see a dialog telling you to update to the latest version. Close GMS2.
  5. In fiddler you should see a session with the URL of "http://gms.yoyogames.com/update-win.rss" click on that and then click on "inspectors"
  6. Once in the inspectors go to the bottom table and click "Text View" copy the XML that you see
  7. Create a new file on your desktop and call it "gms-xml.rss" paste the XML into that file
  8. Still in the "gms-xml.rss" file remove all "<item>" tags or all of the "<channel>" tag contents. You should end up with something like this
  9. Click the "AutoResponder" tab in fiddler and click "Enable rules"
  10. Click "add rule" on the bottom enter the first text box you see and paste "EXACT:http://gms.yoyogames.com/update-win.rss". In the next box type "C:\Users\*your username here*\Desktop\gms-xml.rss"
  11. Now open GMS2 again you should no longer see the update notification, however when you try to login you should get "Error (35)" the next step will hopefully fix that.
  12. Close GMS2 again and enter Fiddler then in the right click "FiddlerScript"
  13. Click the selection box next to "Go to:" and select "OnBeforeRequest". Insert this code into "OnBeforeRequest" (make sure the versions are correct)
  14. Open GMS2 with any luck you should be able to login successfully!
I know that seems like a lot, but this is the only time you have to do it. Although keep this in thought you have to update the FiddlerScript every-time a new version is launched and Fiddler must be opened for you to login without errors.

  3. I've walked through the video and this blog post and still can't seem to get it right. It still gives an update popup as well as a login one. If you could help me out and see where I've messed up, I'd be greatly appreciative.

    Here is a imgur album showing the current settings I have: https://imgur.com/a/1z124pi.
