You can use this method for all the timed achievements.
You will need a wired turbo controller and either of these games, Shark, Shark, Road Fighter, Super Cobra, Red Baron, Astrosmash or Finalizer.
What I do is get a bit of Blu tack, stick the A button down with the Blu tack and get a small pebble, place the pebble on top of the Blu tack to make sure the button stays depressed.
With these games, you will get a couple of minutes play each life and with the A button pressed down, when you do die, it will automaticly start a new game.
Play in ranked mode and this will also get you the time spender medal for each game :)
