Brink, one of the newer id Tech games running under the engine idTech4 still keeps to the original roots of the idTech engine. I had a hunch that the console would be easily unlocked with just a keyboard. Well they did better than that to leave a console fully enabled in the game…or did they?

I started to mess around with Brink, reversing the engine and comparing it to the previous idTech games. They are very similar with huge improvements and very good work done by the guys at id software. Just for personal use I wanted to be able to run my console commands just like on the PC version.

The console command that gets pushed through the engine to “show” the console is “com_allowConsole” or “com_allowFullConsole”. With experimenting with this engine, I found out that the button binds are re-loaded from a .cfg file within the files inside of the games archives. I did not to very much research into the game archives, BUT all hope is not lost. If you were to search for the string “com_allowFullConsole” you can find where a cvar list is generated with defaults and pointers to game code to execute similar to Call of Duty (Quake 3 Engine). The engines are similar in the way that they handle cvars.

Some patches were created to have all of the debug output that gets suppressed in the retail versions of Call of Duty to get spit out over a custom console. This is just an output that was created. The patch is also included with the debug output. You will need xorloser’s xextool and TheFallen93’s xepatcher tools to compile this patch on to a clean xex. The patches were created by kiwidog (http://allenthinks.com)

Here is the patch.
