Notes:
Basically a sequel to the first Super
Volleyball arcade game in 1989.

I've noticed that when downloading all
of the ROM sets of this particular game.
There were other 2 soundchips running with
the same game, but different ROM sets. Of
course, those two soundchips from the
other ROM sets are bootleg.

Like this italian bootleg of this game called
"1991 Spikes" that uses YM2151. This version
have different music composition, rather than
just relying on the 2610's music composition.

I've been numerously searching about this
games' composer, but sadly, I have no luck
to find information about this game. As this
game doesn't have staff roll, or credits in
it, I just gonna have to leave it unknown.

I can basically access the service mode of
any of these games, except on the bootleg
OKI version, where the service mode is
labeled unused. But, to my surprise. I can
basically access it by messing up the
memory addresses from the RAM of this game.

tbh, when I started to log this game, the
sound itself is much quieter. The same effect
goes to the other version of this game that
has the same soundchip, than the YM2151 and
the OKIM6295 one.

Track names are taken from the KHInsider game
rip of this game.
