Hmmmmmmm. I have a theory.
Though they are all the same game, there are multiple "versions," if you will, of Double Dragon (Neo Geo tournament fighting game). There's an AES cartridge, an MVS cartridge, and a CD-ROM. I suppose they just listed all of those because they're technically different storage formats. For instance, some Famicom games were on both cartridge and floppy disk if I recall correctly. It would be no different than creating two listings for those Famicom games: one for the cartridge format, and one for the floppy disk format.
It may be redundant, but it lets people know that there were different formats you could buy, sort of like getting a Genesis or SNES version of a game.
