/***************************************************************************
Beast Busters A9003 (c) 1989 SNK Corporation
Beast Busters is a large dedicated (non-jamma) triple machine gun game,
the gun positions values are read in an interrupt routine that must be
called for each position (X and Y for 3 guns, so at least 6 times a
frame).
----------------------------------------------------------------------------------------
Stephh's notes (based on the games M68000 code and some tests) :
1) 'bbusters'
- Country/version is stored at 0x003954.w and the possible values are
0x0000, 0x0004 and 0x0008 (0x000c being the same as 0x0008), 0x0008
being the value stored in ROM in the current set.
I haven't noticed any major effect (copyright/logo, language, coinage),
the only thing I found is that the text relative to number of coins
needed is different (but it's a lie as coinage is NOT modified).
So my guess is that if other versions exist, part of the code (or at
least data in it) will have to be different.
Anyway, here is my guess to determine the versions (by using some infos
from 'mechatt' :
Value Country
0x0000 Japan
0x0004 US?
0x0008 World? (value stored in the current set)
0x000c World? (same as 0x0008 - impossible choice ?)
- Coin buttons act differently depending on the "Coin Slots" Dip Switch :
* "Coin Slots" Dip Switch set to "Common" :
. COIN1 : adds coin(s)/credit(s) depending on "Coin A" Dip Switch
. COIN2 : adds coin(s)/credit(s) depending on "Coin B" Dip Switch
. COIN3 : NO EFFECT !
. COIN4 : NO EFFECT !
. COIN5 : NO EFFECT !
. COIN6 : NO EFFECT !
. SERVICE1 : adds coin(s)/credit(s) depending on "Coin A" Dip Switch
* "Coin Slots" Dip Switch set to "Individual" :
. COIN1 : adds coin(s)/credit(s) for player 1 depending on "Coin A" Dip Switch
. COIN2 : adds coin(s)/credit(s) for player 1 depending on "Coin B" Dip Switch
. COIN3 : adds coin(s)/credit(s) for player 2 depending on "Coin A" Dip Switch
. COIN4 : adds coin(s)/credit(s) for player 2 depending on "Coin B" Dip Switch
. COIN5 : adds coin(s)/credit(s) for player 3 depending on "Coin A" Dip Switch
. COIN6 : adds coin(s)/credit(s) for player 3 depending on "Coin B" Dip Switch
. SERVICE1 : adds coin(s)/credit(s) for all players depending on "Coin A" Dip Switch
Note that I had to map COIN5 and COIN6 to SERVICE2 and SERVICE3 to be
able to use the default parametrable keys. Let me know if there is a
another (better ?) way to do so.
----------------------------------------------------------------------------------------
RansAckeR's notes:
bbusters:
If you only calibrate the P1 gun or do not hit the correct spots for all guns
you will get either garbage or a black screen when rebooting.
According to the manual this happens when the eprom contains invalid gun aim data.
If you calibrate the guns correctly the game runs as expected:
1) Using P1 controls fire at the indicated spots.
2) Using P2 controls fire at the indicated spots.
3) Using P3 controls fire at the indicated spots.
The locations of the shots fired in attract mode are defined by a table
starting at $65000. The value taken from there is combined with data from
the gun calibration to calculate the final position of the shots.
Unexpected calibration values will therefore cause the game to show the
shots in weird positions (see MT07333).
The EEPROM data starts with the 16 bit calibration values for all six axes
in the order: Minimum axis 0, middle axis 0, maximum axis 0 (repeat for
the other 5 axes).
----------------------------------------------------------------------------------------
Beast Busters Region code works as follows
ROM[0x003954/2] = data * 4;
Country/Version :
- 0x0000 : Japan?
- 0x0004 : US?
- 0x0008 : World? (default)
- 0x000c : World? (same as 0x0008)
