If you must cheat then
these are the codes you should use.
Enjoy, even though I recommend playing the game legit first.
*1438-7765 - INVINCIBILITY 3 All enemies die if you attack, or if they attack. Great if you are in a hurry.
39B0-EFA4 - Walk thru Walls (Only places that are accessible) Use this code to avoid enemies and walk through sealed doors (Like in the Bangor Dome). Skip half of the game by going to the Keeper's Dome and getting Epoch even before getting Robo in your party! Skipping areas can also be done in other parts of the game.
3CB5-5FD3 - Silver pendulum at title screen.
DCCB-57FE - Strange music, and sound FX.
00C0-57FE - More strange music and sound FX.
0082-E707 - Play Jet Bike race at title screen.
4282-E707 - Time warp graphics at title screen.
333B-EF00 - Skips Exp. screen after a battle.
F76E-5F00 - Characters automatically run away when you enter a battle. You can even run away from bosses! One negative about this code is that it only seems to work if you start a new game.(Or new game +).
7F67-5DD0 - Play Dead. Go into battle with the GG turned on. Notice that the HP numbers of your characters will be messed up and the game will act like it froze. Now turn the GG off and your party members will fall down as if they had died. The enemies will disappear and your characters will get back up. Then the game will continue as if you had beat the monsters. Works on bosses also! This code seems to work better then the one above.
EE34-5D60 - Attacks do more damage in battle. However, it doesn't increase damage when using magical attacks.
22B4-546B - Get the losing Ending! Leave GG off until you enter a building in Truce 1000 AD. Turn GG on and leave building. You will get the "Map" screen. Turn GG off again and watch the losing ending.
DIFFERENT CHRONO TRIGGER VERSION!!!!
If these codes don't work on your game pak, you probably have a different version of the game. You can get these codes to work, but you will have to change the code.
3BC4-7765 - Fleeing Enemies. Enemies will try to run away from you in battle. This will not work on stationary monsters and Bosses!!! Some monsters will start to fight you if you attack while they are trying to run away. Some monsters will glitch the game.
B323-7765 - Invincibility. This will make you and the enemies INVINCIBLE in battles.
B623-7765 - 9999 points Damage. This works for both you and the monsters!!!! Beware.
B625-7765 - Evade Increases. his code makes it really hard to "attack" monsters and vice-versa. The chances are 1 to 10 of getting hit!! This does not work on "techs" though.
EEE3-7765 - Decreasing Damage. For the first few rounds of battle the damage that is dealt to you increasingly goes down. (for instance I was fighting a Laser Guard outside The Black Omen and it zapped Crono, first it did 109 damage then 100 then 75 and so on) then in the later part of the battle it seemed as if the code quit on me and the damage taken started rising again. I`m trying to get it to perfection so that the damage eventually hits 0.
22EC-ED60 - Gain all techs after one battle.(Get ready to tape the A-button down!)
A523-7765 - Assorted damage. Sometimes you take 0, sometimes you take normal amounts, Ignore the disappearing characters.
Notes: If the first code doesn't work, try the second one.
