Mad Motor

A 1989 prototype / unreleased game made
by Mitchell, notoriously known for the
games like Buster Bros., Super X (Mitchell
licensed), and much more.

Rumors said that it's basically Road Rash-
beat'em up hybrid game, where the player
is getting hit by the enemies, It would go
transforms into a wolf, which is super cool!

This is also used some PCB parts, design, some
routines from Data East, according to the
machine source code (madmotor.cpp) of this
game.

This game was using Dark Seal's sound
hardware. Yet, I can't figure it out what
the correct sound clock speed was. Since
MAME emulation and M1 have differences in
terms of speed.

Example, take a listen on the "Credit SFX".
This pack was a little bit faster than the
M1 version of this game. Since MAME playing
the same "F" note 6 times, while the M1
version seems to be played 4 times. But to
my surprise, it seems it doesn't play 6 time
on this pack.

For me. I would prefer this faster version
OST of Mad Motor, rather than listening the
M1 version of this, because it is slower than
this pack.

HuC6280 are unused in this pack, because I
think it is responsible for the sound CPU
registers. The only thing they used for
sounds is these 3 soundchips. YM2151, YM2203,
OKIM6295, just like Dark Seal's VGM pack.

Credit SFX is only used for YM2203 only, the
rest is using YM2151 and 1 OKIM6295, because
the other OKI chip was used for voices and
SFXs too.
