D-1 Grand Prix Taikenban SLPM80558

This software was given as a privilege item along with Digital Partner & Wonder Wave Doukonban (bundle). From what I understand, you can transfer Digimon from Wonderswan to PlayStation to have them fight in a 3D mode. This mode (D-1 Grand Prix) was developped further on between games of those consoles and then gave birth to Challenge D-1 Grand Prix 2001 mode.

Details about game compatibilities here.
