Sadly it has reached the point where Nintendo has a huge back catalogue & they merely push old games a 2nd time onto new hardware. This philojusophy will only carry you so far. Forrtified Zone and all other et al possibly multiplayer games are merely emulated to 3ds with no additional features beyond the original. The programming/coding for original GB games is more than well understood at this point so what possible legal reason would exist which would prevent Nintendo to add additional content to an extremely old title. Nintendo needs to look towards the future. Releasing their wii version of Castlevania or Wii version of Contra with 3D enhancements (which requires an extremely simple programming intervention) is more along the lines of what fans deserve.
