Wedding March is a song written by Felix Mendelssohn in 1842. It was written for Shakespeare's A Midsummer Night's Dream. It has since been used in several weddings even to this day.
Because the song is public domain, it has been used in several video games.
Games
Libble Rabble (ARC)
Friday the 13th (C64)
Creative Music System (DOS)
Haunted Castle (ARC)
The song is played during the introduction sequence and is rendered on the cabinet's Konami SCC chip.
King's Quest II: Romancing the Throne (DOS)
The Wedding theme starts with the first couple bars of Wedding March, but switches to Richard Wagner's Bridal Chorus once its opening finishes. The song is Sound.001 in the game's data files.
Dr. Jekyll and Mr. Hyde (NES)
The song plays during the game's ending sequence.
During the ending, we see the good doctor and Ms. Millicent meet at the church. Walk toward each other very slowly, and then go inside the church. The text END is then displayed. If the player beat Letule as Mr. Hyde, then the song will be interrupted by an alternate ending of a silhouette of Hyde.
Yuuyuu Jinsei (PCE)
The song plays during the marriage cutscene.
The album Kinoko Kunimoto Takeaki History Vol.5: Katoken titles the song Kekkonshiki (結婚式 = Wedding).
There seems to be an error where one of the instruments is a 16th note out of sync with the rest of the instrumentation.
Takeaki Kunimoto originally arranged the song on his Yamaha CX7 MSX2 computer using FM Music Composer II. It was then coded into Takayuki Iwabuchi's sound driver by Toshiaki Takimoto.
Vegas Dream (NES)
Street Fighter II: The World Warrior (ARC)
The second part of Ken's ending (wherein he marries his love interest) features an arrangement of the song for the CPS-1's YM2151 chip. Only a small portion of it plays in-game, though the full version can be heard in the machine's sound test (where it can be found under the numerical ID "34").
This version is reused without any changes in Street Fighter II': Champion Edition (ARC) and Street Fighter II' Turbo: Hyper Fighting (ARC).
The song is simply titled "Ken's Ending 2" on the album Street Fighter II The Definitive Soundtrack. Other releases of the music, such as Street Fighter II Turbo + Street Fighter II Dash Plus Original Soundtrack, append the parenthetical subtitle "(Wedded Bliss)" to this name.
Hocus Pocus (DOS)
Zeppelin: Giants of the Sky (DOS)
