This is a bundle product featuring “Monster Rancher” and “Monster Rancher 2” at a discounted price.
The content of the bundle is identical to “Monster Rancher” and “Monster Rancher 2” available for individual purchase.
That feature was only for the PlayStation. You visited a shrine and the game would ask for a music disk.
The game would then generate a monster from the meta data of that disk.
For the iPhone, you can still visit that shrine, but instead of asking for a disk, the game would ask for an artist name.
The great thing about the Song List on DX is that now everyone has access to every monster in the game, rather than being limited by a personal collection of CDs. (You still have to make your own unlock progress in-game of course).
The entire Song List for MR1&2DX has been solved too! LegendCup has an app to pick a Main breed and Sub breed and see every unique variant of every possible pure and mixed breed now as well. (Or you can use the "Random" button if you live for the thrill)
