In Windows, you can use Start Menu>Run to run the above command, and I think you can chdir to the correct directory and do the same thing in the command prompt. On other systems, just use Terminal.
Also, you can create a shortcut to collider.exe, and where you set the target (collider.exe), change it to the above code.
It will run, and hopefully collide it without errors. Then, you can play. If the scripting is right, then you'll be able to use the cheats you made without causing a desync.
