Riding Fight composer?
 

Riding Fight is an arcade game from Taito (1992) for their "F3" hardware, the game has no in game credits from what i can see.
It seems not to have got an OST release either... although i was sure i had seen it in one of Taitos later game music compilations OST releases but must have mixed it up with another game?

riding fight video game, taito corp. (1992)

It seems to be "Yasuko Yamada" Yasuko Yamada - VGMdb

I played the world version of the game and it did not have any credits but then i tested the japan version and it did display credits at the end... i had some help translating of course.

here are some screenshot i did from the credits in case anybody else want to see:

The only sound credit I found in there is at the bottom of 316.png, where Yasuko Yamada is credited with "音響技術." That means something like "sound engineering," so it doesn't necessarily mean composition at all, but I didn't see anyone else credited with music.

Some credits had (VAP) next to them what do that mean?
And what is "Revolutions"?

I agree it can't be certain that Yasuko is the composer but as you mention she is the only one with sound credits at all.
Does the other credits reveal if the game is by Taito people?
