Game versions are locked to a specific console, on a generation with some faulty hardware. The trend nowadays is to re-release games for newer generation. The re-release is technically a different game, so it might require another music license, so it might not have the same soundtrack, it changes the feel of the game. The old console has its time ticking. Without emulators, that game experience won't be preserved, its simply at the whims of executives which don't really care enough about such small details for re-releases because the name of the game is usually enough to make some bucks.
