You can access the codebase by going to the TGC home site and pointing to the 'Community' box. A drop-down menu will have the codebase on the list. You also could look at the code snippets (click on the 'My Threads' down arrow above and the code snippets are in the menu). This should give you some code that could help you put a game together fairly quickly.
I made a Space Invaders game a while back that might give you some ideas. I have attached the code and media in a rar.zip file. If you do not have this program you will not be able to access it. The WinRar site is

You can download a trial version of Win.Rar there.
The game is probably 95% complete with mainly the top ten scoring to finish. Also, it is programmed for a joystick. If you want to use a keyboard, you could plug in the keypresses in place of the joystick commands.
I never did get around to putting in a keypress to mute the music during game play. This would be easy to do, I just never did it.
Hopefully these things will help you to get something together.
You idiots! You've captured their stunt doubles!
