A Better Tomorrow
A Better Tomorrow is the ending music that plays in the Japanese releases of Bad Dudes, known as Dragonninja. The US releases play Hail to the Chief.
The official title come from the Deco History: Data East Game Music Scene One album where the song is named 男たちの挽歌 (Otoko Tachi no Banka) which, at least in a Chow Yun-fat action movie title (which may have been the inspiration), translates to, "A Better Tomorrow."
Bad Dudes vs. Dragonninja (ARC)
This is the original version of the song. It is rendered on the game's YM3812.
Both the Japanese and US releases of the NES port feature the American ending which plays Hail to the Chief. The Amstrad, C64, and Spectrum ports have different soundtracks that don't include this song. The Apple II, DOS, and MSX ports do not have music.
