Notes:
This is basically a OKIM6295 version of the
game, converted by the bootleggers. I don't
how they did this, maybe some recording.
This version is basically doesn't have a
full loop on some of the tracks, some of
them are cutted due to the limited space of
the chip, and the sound test of this
version is really, really broken. I have to
reset the game before I play the next track.

On the second set of this bootleg,
Mediterranean Sea was also cutted in this
version.

One thing about this game is, I freaking
love Mao-Mao!!!

Track names are taken from "SONIC WINGS
-VIDEO SYSTEM ARCADE SOUND DIGITAL COLLECTION
Vol.1- [CLRC-10019]".

Note: This pack uses ADPCM streams and seeking
doesn't work properly.

Regarding the v1.10 fix:
The original logs suffered from a race
condition that caused the songs to be partly
muted.
The game waits until the stream ends and then
immediately issues the next "play" command.
However the OKI6295 ignores these "play"
commands when the channel is already playing.
Due to the VGM's tick resolution of 44100 Hz,
it could happen that the "play" command was
issued by the VGM when the channel was just not
yet finished, causing the rest of the song to
be muted. I patched the VGMs to always
explicitly stop each channel before issuing the
next "play" command.
