How do you get new Digimon on Digimon World 2003?

Answer 1

To get new Digimon beyond your original 3, you must find DRI Agents scattered around the world. There is really only one requirement: to have strong/weak enough Digimon for the DRI agent to talk to you (make sure to get the extra Digimon early in the game, because they may not talk to you if you have the proper requirements later in the game). If you have the proper requirements, and talked with a DRI agent, you will have to collect data from an ultimate Digimon. The Digimon depends on the DRI agent. When you find that Digimon, you must battle it. When you win, you will get the data, then return to the DRI agent and you will get the rookie form of the Digimon you fought. You can obtain all the Digimon from the original starter sets, along with Veemon.

Answer 2

I believe if you get level 18 or 19 you get another beginner and you can do this to get all the starters you were able to choose the start. The other ones you have to beat the game and do some certain things to acquire them you can easily find the list of you look it up by typing "digimon world 4 cheats" or "digimon world 4 unlockables"

Answer 3

Every time you meet a wild Digimon (excluding bosses) you will get an amount of scanned data from that species. Once you met a Digimon enough times to accumulate at least 100% of its scanned data, go to the Digifarm and select the option to convert it into a Digimon for you.
