NG OUT THIS UPDATE - THE ADDITIONAL INFO
COULD BE..INTERISTING FOR YOU ASWELL...
..V1.0 PRELUDE..------------....AT MEKKA
SYMPOSIUM 99 WE TOOK A LOOK AT THE 4-PL
AYER ADAPTER THAT IS SUPPORTED..BY THE G
AME "BOMB MANIA". THOMAS AND BJOERN HAD
STARTED WORKING ON THEIR..PROJECT "DETON
ATORS 2" A WHILE AGO AND THE MULTI-PLAYE
R ABILITY WAS PUT ON THE.."MUST HAVE" LI
ST. HOWEVER, AFTER WE CRACKED UP THE THI
NG WE NOTICED THAT THIS..PARTICULAR ADAP
TER NEEDED SOME ELECTRONIC COMPONENTS TO
WORK AND BECAUSE OF..THAT IT WAS NOT RE
ALLY SUITABLE FOR THE AVERAGE SCENER TO
BUILT ON HIS OWN. WE..ALMOST FORGOT ABOU
T THE IDEA OF CREATING A 4 PLAYERS THING
Y, UNTIL WE MET AGAIN..AT THE END OF NOV
EMBER 99. HAVING NO DECENT DOCUMENTATION
EXCEPT SOME SCANNED..C64 SHEMATICS AND
SOME IO-MAP IT WAS QUITE A HAZZLE TO KNO
CK IT UP SINCE WE HAD..TO DISCOVER A FEW
(PROBABLY WELL KNOWN) THINGS OURSELVES,
BUT WE FINALLY WORKED..IT OUT. HERE IT
IS, EASY TO BUILT FOR EVERYONE - AND DOC
UMENTED ASWELL.....TAKE THIS AS OUR CHRI
STMAS PRESENT FOR YOU - SINCE IT IS CHRI
STMAS ANYWAY,..SPEND YOUR TIME ON SOMETH
ING USEFUL AND DO SOME CHRISTMASSY HANDI
CRAFT WORK.....HOW IT WORKS..-----------
-....TO INTERFACE 2 ADDITIONAL JOYSTICKS
WE HAD TO FIND 10 ADDITIONAL INPUT-LINE
S..ON THE C64. SINCE WE WANTED TO CREATE
SOMETHING THAT IS BOTH CHEAP AND COULD.
.BE BUILT BY PEOPLE WITH VERY LITTLE (IF
NOT NONE) SOLDERING EXPERIENCE, WE..LIM
ITED OURSELVES TO JUST USING PLUGS AND W
IRES. WE LOOKED AT THE USER-PORT..AND FO
UND 8 LINES AT THE FIRST GLANCE - PORT B
OF CIA 2 - WHICH WERE USED TO..CONNECT
THE 4 DIRECTIONAL LINES OF EACH JOYSTICK
. FINDING 2 MORE LINES FOR..THE BUTTONS
WAS A LITTLE MORE TRICKY. IF YOU LOOK CL
OSER AT THE USER-PORT,..YOU WILL NOTICE
THAT BIT 2 OF CIA 2 PORT A IS CONNECTED
TO IT ASWELL, SO..THERE IS JUST ONE OTHE
R LINE LEFT TO FIND - WHICH TURNED OUT T
O BE THE MOST..CHALLENGING PART OF IT AL
L. WHAT WE DID IS ABUSING THE SYNCHRONOU
S SERIAL..DATA REGISTER OF CIA 2, WHICH
IS ALSO AVAILABLE AT THE USER-PORT. TO M
AKE..THIS WORK WE HAD TO LET CIA 1 OUTPU
T A COUNTER-SIGNAL AT THE CORRESPONDING.
.USER-PORT PIN AND WE FED THAT SIGNAL BA
CK INTO CIA 2 SERIAL-COUNTER. NOW BY..US
ING THE MAXIMUM COUNTER-SPEED POSSIBLE,
WE COULD USE THE SYNCHRONOUS..SERIAL REG
ISTER OF CIA 2 AS ANOTHER 'DIGITAL' INPU
T LINE AND BINGO - THERE..WE ARE........

----------------------------------------
---------....KNOWN PROBLEMS:..----------
-----....THERE IS, HOWEVER, SOME MINOR P
ROBLEM WITH PROGRAMMING A GAME THAT SUPP
ORTS THE..ADAPTER. IT IS, THAT IF THE AD
APTER IS NOT CONNECTED TO THE C64, THE C
ODE AS..SHOWN HERE WILL ALWAYS REPORT FI
RE ON JOY4 PRESSED. SO IF YOU WANT YOUR
GAME TO..WORK WITHOUT THE ADAPTER ASWELL
, YOU NEED A USER-INTERACTIVE OPTION TO
SWITCH..THE ADAPTER-READING CODE OFF. (O
R IGNORE WHAT IT REPORTS RESPECTIVLY. AL
SO,..YOU SHOULDNT USE FIRE ON JOY 4 IN M
ENUS OR SUCH THINGS LIKE 'START GAME' IF
..THERE ISNT A WAY TO SWITCH THE ADAPTER
OFF BEFORE (THE GAME WOULD BE UNUSEABLE
..WITHOUT THE ADAPTER).....LAST WORDS:..
-----------....WITH THIS THING WE HOPE T
O MOTIVATE SOME MORE PEOPLE TO DEVELOP M
ULTI-PLAYER..CAPABLE GAMES FOR OUR BELOV
ED MACHINE. SEVERAL GAME CONCEPTS DO JUS
T CRY FOR..AN EXPANSION LIKE THIS! IT'S
UP TO YOU NOW... MAY IT BE PATCHING EXIS
TING..GAMES (LIKE ALL THOSE ROUND-BASED
SPORT GAMES FOR EXAMPLE) OR CREATING..AS
