Cheats for Digimon World 3 (PS1)
New partner Digimon
There are eight partner Digimon you can get. They are Agumon, Patamon, Veemon, Guilmon, Renamon, Kumamon, Kotemon, and Monmon. After the first three you get, you will need to find the Ultimate level Digimon for the rookie that you want. DRI people are in various locations and they will tell you which Ultimate Digimon they want DNA from. Defeat the Ultimate level Digimon to get the DNA. Take it back to the DRI person that wants it and you will get that rookie. For example, talk to DRI person in Tyranno Valley. He wants DNA from MetalGreymon. Go to Bulk Swamp to find MetalGreymon. Fight and defeat him to get the DNA. Take it back to the DRI person and he will put Agumon in your team. Go to Digimon Lab or see Piximon to switch to Agumon.
Permanent Digimon
Use the following trick get permanent Digimon such as Paildramon or Omnimon. For example, to get Paildramon permanently you must have a Digimon that can digivolve to Exveemon and Stingmon at level 5. To get Omnimon as well you must have a Digimon that can digivolve to Metalgarurumon and Wargreymon at level 40.
Experience for all
Tag in all your weaker partners first, then tag in your strongest last. Do not forget to heal them to get the experience. Then, finish with the strongest Digimon. All the digimon will get the same amount of experience.
Cardmon
When fishing, land and stop on the yellow space all the way. Otherwise, you will just get the local Digimon in the water there. If you cannot land on the yellow, land on the other color (blue) and you will be confused, You can then try again without fighting.
Digmon
After you defeat the Sazaku leader in the Amaterasu server, talk to the Pi where Renemon stood in the Asuka server. He will move aside. Then, go to the dock to the Ug lake. At the very top is the Digiegg Of Reliability. You can call Digmon whenever you are at a hole with red dirt around it.
Submarimon
Get the Digi-Egg Of Sincerity. You can now call Submarimon from any dock. The docks are the strange little square things. A "!" will now appear and you can call Submarimon. There are mostly Dolphmon and Gesomon in the Seabeds . Make sure you are at least level 15 before attempting the Seabeds.
Veemon
When you are playing hide and seek, never leave Kicking Forest or you will not be able to get the boots. From the entrance at the left set of trees, go down. Sometimes it is in the lower section. To find the Veemon to get the Tree Kicking Boots after the girl in Plug Cape tells you about them, go to the Lamb Chop. Talk to the waitress that is not behind the counter, She will tell you to go to Windy Trail to find the Veemon. Look under the first few trees by X under them. You will eventually find him.
Wargrowlmon
To get the Wargrowlmon's DNA, it can be found in the Ether Jungle.
Alternate forms
You can get alternate forms to your Digimon's Rookie. The first will be at level 5. Champions seem to grow in levels faster than Rookies. Depending on your tolerances, you will get other forms as well.
Signature attacks
Champions get their signature attacks at levels 60 to 74. Ultimates learn them at level 75 to 80 or 85. Megas learn them at level 81 or 86 to 99. Also, BlackWarGreymon has a different name but a simillar signature attack. WarGreymon's signature attack is Terra Force, but BlackWarGreymon's signature attack is Terra Destroyer. There maybe other similar occurrences in the game.
Easy experience
Tag in all your weaker partners first, then tag in your strongest last. Do not forget to heal them to get the experience. Then, finish with the strongest Digimon. All the digimon will get the same amount of experience. Note: This trick requires a controller with a auto-fire feature. Go anywhere where you can kill the enemies in one hit with attack. Set the auto-fire to X and use a rubber band to keep X and the D-pad held. Allow the game to remain in this condition for an extended amount of time.
Attack twice occasionally
Sometimes you can attack twice. One way is to get your opponent's health to the reds. The second method depends on your speed/movement.
Evade
Hold X just before an attack hits. If timed correctly, you will block the attack most of the time.
Retreating
If you do not want to battle and just want to get to a save location, place your strongest Digimon in front. When you get to a battle, it will hopefully be strong enough to allow you to run away.
Training
When you are training your Digimon, quickly press Circle repeatedly and he should get it correct most of the time.
Gabumon card
To find the Gabumon card, look in the boxes in the Inn in Asuka City that are being cleaned.
Tree Kicking Boots
