First, Close out steam fully. Then, you want to launch steam in dev mode. This can be achieved by running steam with "-dev". You can do this by going to the properties of your steam shortcut, and adding -dev to the target field. Make sure to apply.

Now, your steam client should open up, and you should see console along the top, if you don't, make sure you applied the changes to the shortcut!

Next, go to your profile. Press edit profile, and go to the featured showcase section.Then pick a random game for the moment. I chose Unturned, but any game should work.


Next, press F12, or CTRL+SHIFT+I to open the DevTools inspect element thing. It should pop up a window that looks like this. Then, click on this little box with the cursor, circled in red in the picture.

Then go back to steam, and hover over the game box, and click when it looks like this (Mouse about where the red dot is).
Then go back to your DevTools Inspect element window, and either click the menu, go to tools, and search, or press CTRL-F. This will open a little search box at the bottom of the window.
Search for "input".
The first line to pop up should look like this, and most likely with a different "value" based on whatever game you chose earlier.


Next, you want to double click on the number
after "value", and replace it with 1232180 . Now, go back to steam, and click save.


Then you should see SIGYAAD as your favorite game!
You can replace that number with the game id of any game you want, but 1232180 is the game id for SIGYAAD. Hope you enjoy! As far as I know, Credit for this technique goes to "Tev", as he listed the steps here https://test-steamproxy.haloskins.io/discussions/forum/1/2906376154313230797!

Don't forget to remove the -dev from the shortcut if you want, although it isn't necessarily an issue.To
