Unfortunately, I don't know what code is for a star in a checkpoint, for this reason I'm using a generic checkpoint.

What is it?
It's a mod that able you to press a button and write the command, like the Valve's games console.
This version have 14 commands, that can be found in the readme-NativeConsole.txt.

Feel free to suggest a command, that will make the mod better.
