Invincibility
In "Ed, Edd n Eddy: Jawbreakers!" the three Eds contend with travails and enemies as diverse as bottomless pits and house dogs, all of which deal damage to the characters. To avoid any damage whatsoever, activate the invincibility code. From the start screen, hold the "L" and "R" buttons at the same time and press "Left," "Left," "Right," "Down," "Down," "Up" and "Right" to enable this cheat.
Level Select
To attain the everlasting jawbreaker, you'll have to guide each of the three Eds across six different levels. If you find yourself at an impasse, go to the start screen and hold "L" and "R" simultaneously. While still holding the triggers, hit "Left, "Left, "Right," "Down," "Down," "Up" and then "Right" on the directional pad. This enables "level select" mode, allowing you to play any level in the game instantly.
All Items
"Ed, Edd n Eddy: Jawbreakers!" puts a handful of items -- such as slingshots, tools and the hypno-disc hat -- at the brothers' disposal. Instead of collecting the items one at a time, you can instantly unlock them all by going to the start screen, holding the "L" and "R" triggers and entering "Left," "Left," "Down," "Right," "Right," "Up" and "Left." In the game, Edd uses the tools and slingshot while Eddy uses the hypno-disc hat.
Unlock Jet Pats
Normally, only Eddy can use the jet pack item, which allows him to fly through the air and all over the game screen. To unlock jet packs for all the Eds, hold the "L" and "R" buttons simultaneously at the game's start screen. In order, enter "Left," "Up," "Right," "Down," "Left," "Left" and "Up."
