Re: What are the differences???

It depends on the game. According to the Beyblade wiki, that game has special Beyblades that you could only get with specific versions of the game.

Ive found some roms that will have the standard, then a few others that say stuff like "this store exclusive" or "collectors edition" what is the difference? For example, Beyblade Metal Fusion for the DS has the regular, then it has "Collector's Edition," "Walmart Exclusive," and "Toys R Us Exclusive." Wht is the difference between all these???
