Info
----
This is the source for the "bubble bobble sound patch" for 
MAME final version 0.35. Just unzip (-d) the source files
into their respective directories and recompile. In order
to use this patch you will have to recompile MAME yourself.
The MAME licence prohibits distribution of modified binaries.

This sound patch will give you 100% accurate sound in
Bubble Bobble + clones using samples from the arcade machine.
It will also let you play Bobble Bobble with 60 FPS + sound 
on a P133 since most of the sound CPU's are not emulated. 

Samples
-------
The samples were taken from Andies original Taito PCB
board using the "service mode" to produce each sound. The
old sample set is no longer supported due to it's
inferior quality.

Compilation
-----------
Before recompiling run "make bublbobl". This will make sure
that the project is recompiled correctly. 

Source Changes
--------------
In order to get the sound playing as cleanly as possible I've
had to modify the function "msdos_update_audio()" in
src/msdos/sound.c slightly. Instead of using AUpdateAudioEx()
I use AUpdateAudio(). This might affect other games.
