How to Enable The Developer Console
To enable the console, first, you must quit the game.
Once you have quit the game, go to the directory of your Portal Reloaded game.
(This is usually C:\Program Files (x86)\Steam\steamapps\common\Portal Reloaded)
Once you are there, Enter the “portalreloaded” folder and open “config.cfg” with a text editor of your choosing. Proceed to press CTRL + F and look for “con_enable” and it should have a “0” afterwards. Set this to 1. The next step is crucial.
Stopping the mod from overriding.
By default, when you launch the game it will set the “con_enable” string back to “0”. To circumvent this, simply right-click on the config file and hit Properties, and click “Read Only” checkbox at the bottom.
WARNING: ANY CHANGES YOU MAKE TO YOUR SETTINGS WILL NOT BE SAVED AFTER THIS.
Now the game will be unable to stop the console access and you can open the console with your desired key which can be changed in the options in-game.
