Morihiro Iwamoto

Yes! There is also a new Bomberman game out for the Nintendo Switch known as Super Bomberman R. However, sadly according to Wikipedia it isn't composed by Morihiro Iwamoto but rather Seima Iwahashi and Daisuke Kikuta.

In Densetsu no Stafy 4, there are many unusual unused graphics and one of these is a sprite-sheet that appears to be from Namco Museum Battle Collection.



Taking a look at the composer of that game, Namco Museum Battle Collection is also said to be composed by Morihiro Iwamoto; furthermore Yasuhiro Minamimoto is one of the staff, attributed under System & Arrangement Games: Producer; so that brings light to why the spritesheet can be found unused in the game's data.

Furthermore, Morihiro Iwamoto may have worked on Mega Man X7 for PlayStation 2 and Deadly Promonition for Xbox 360 according to MobyGames.

I don't know if this is true, but additionally the Canadian Copyright Office apparently requests staff lists for works (according to NinDB, a Nintendo game database). It was this way I found out a long time ago that Morihiro Iwamoto worked on Dr. Mario & Puzzle League, Tingle's Balloon Fight DS and Puzzle Iroiro Gekkan Crossword House Vol. 1 (a really obscure DSiWare game that I can't find the soundtrack to sadly) likely as a composer, as he's listed as one of the authors.

Yes, I haven't played that game but I got the impression it is darker compared to the other games. I think he specifically worked on the lyrics for "Greenvale".

Additionally he apparently worked on composition, arrangement and lyrics but not the vocals of a song called "Will" from Art Camion Geijutsuden.
