Cheats for “Grand Theft Auto” include accessing stage select by pressing left, right, up, down, L, R and then holding Start and A, or turning on cheats by holding A and B and pressing the Start button. Both of these codes work on the Game Boy Advance version.
After turning on cheat codes, the game displays the text “Cheat Modes On.” The location of the in-game character also appears on the screen. With cheat mode on, players can enter in a number of other codes during normal gameplay, such as max health by pressing left, right, up, down, B and B.
When turning on the stage select screen, the player has to be on the main menu. After entering the correct button inputs, the game makes a chime sound. Next, there is a new option on the main menu called Pick Level. Players can also hit the B button on the main menu to bring up the game credits.
There are some useful hints that players can use for “Grand Theft Auto” that don't require cheat codes. For example, once they reach the level six heat, the player should run around trying to stay alive or getting busted. Eventually, a tank appears on the world map for her to use. Inside the tank, she can shoot homing missiles by pressing the A and B buttons together.
