The simplest explanation is that these listings are all for Virtual Console downloads. Prince of Persia was released on both the Game Boy and Game Boy Color, making it eligible for the 3DS Virtual Console -- and it was made for almost all of the platforms supported by the Wii Virtual Console. In addition, a game called "Rayman" was released on Game Boy Color, which was a combination of elements from Rayman 1 and 2 -- and thus providing an example of why we'd have a hard time knowing what the plain "Rayman" title referred to.
