Not so long ago Popolon_fr released a batch of JoySNES patches for several Konami games. He keeps the wheel turning and has more games pending to be adapted for the SNES controller.
Until the next batch sees the light he released a very welcome patch to ease the pain of waiting. From now on you can play Konami's shooter gem Space Manbow with a SNES controller.

He couldn't resist adding a patch for the first game in the Nemesis/Gradius saga, so an extra relevant link is in place:
