This is DMPC or Digimon PC. It's a desktop game that is basically the old Digimon Tamagotchi's, but with a difference. A lot actually. Theres coloured sprites, detailed Tamer ID cards, more involving mini-games for training and the ability to battle your Digimon with others through respective computer I.P addresses.
Not only that, the amount of Digimon available is staggering. All of the old ones are there, Agumon, Gabumon... but now you can also get Guilmon, Veemon and if you're good enough, Gallantmon, BlackWargreymon and even Super Ultimate Digimon. I could go on all day.
