All published and official codes as of Friday May 24, 2013 for Devil May Cry 3 are shown below.
When at the title screen, hold all top buttons and rotate the left analog stick till you hear "Devil may cry". Enter a loaded game and select the costume with Dante's coat open(Super Dante gives you unlimited devil trigger), and "Heaven or hell" difficulty for any level. You can now kill anyone, even bosses with one shot (on doppelganger boss you have to bring him into the light before you can shot him). As for the difficulty you don't get as many red orbs and you can only get hit once. I reccomend buying alot of yellow orbs.
When in the loading Screen you can press the Triangle and Square buttons to shoot or slash the now loading words.
If you don't have enough red orbs saved up to buy the stinger after Mission 1, it's probably a good idea to do Mission 1 over again so you can purchase it. If you do have enough orbs to buy it, it's a good idea to power it up to level 2. This will really help you with the boss battle in Mission 2.
Doppleganger is a late game boss before Dante enters the demon world. Once the battle starts, the room your in will be dark. On the wall there are eye-lid like things. When Doppleganger attacks you dont bother hitting him because it wont work. Instead hit the eye-lid things Three times so they open up revealing light. Doppleganger will stop and you can hit him for a short time. Keep doing this with the other light fixtures. From time to time Doppleganger will shoot one of the lights closed. When you open up all the lights, Doppleganger will be imoble for a long time giving you a chance to attack like crazy. After one of those, doppleganger will return to the center of the room and close all the lights. Just keep opening the light and you will beat him.
To kill the ice demon which is a dog with three heads and uses ice to his advantage,you must first defrost his heads. Use devilarms which is triangle and L2, first. Then get a good distance away and use your lock on target L1 on one of his heads. Fire repeatedly useing square. Do this over and over and eventually he will die. It does take w while though.Also try to avoid the falling icecicles. If they hit you it takes away about half of your life.
