Namco Classic Collection Vol. 1 Cheats

To activate the running timer for Galaga Arrangement, the button sequence is Left, Right, Left, Right, Button 1, Button 2, Button 1, Button 2.

This needs to be done before you press Start at the Galaga Arrangement screen. If done correctly, the Arrangement plaque will dim, and when you begin, a running timer will show up at the bottom of the screen, underneath your ship.

There should be a bonus if you can finish this game fast enough. Found this cheat after I finished the game once.
