NOTE:  I CHOSE APPLE GALAXIN HERE BECAUS E IT IS A WIDELY DISTRIBUTED PROGRA M
, AND IT ENCOMPASSES THE BASIC ID E AS IN BOOT TRACE CRACKING.

FOR ALL THOSE INTRESTED PIRATES OU T THERE, YES THERE IS ANOTHER WAY TO CRA C K
PROGRAMS.  YOU DON'T NEED ANY RAM-CAR DS,PROM BURNERS, OR FOREIGN TO REGULAR D
O S PROGRAMS, ANYBODY WHO IS NOT A CLOWN, WITH SOME MACHINE LANGUAGE PROGRAMMIN
G ABILITY CAN TRACE A BOOT.  THIS METHOD OF CRACKING, TRACEING THE BOOT, IS IN
A

TRUE SENSE, CRACKING THE CODE.	YOU SEE, FOR ALL DISKS, THEY MUST FIRST BOOT UP
T O START RUNNING.  AFTER THE FIRST STAGE BOOT (AT LOCATION $C600), THEY JUMP
TO

SECOND STAGE BOOT PROGRAM (AT $800), AN D THEN TO A THIRD, AND SOME EVEN A
FORTH , BUT THERE COMES A POINT WHERE THE LOAD ING OF THE PROGRAM FROM DISK
STOPS, AND T HE RUNNING OF THE PROGRAM BEGINS.	IF Y OU CAN TRACE THIS, AND
STOP IT AFTER IT I S FINISHED LOADING, AND SAVE ALL THE ME MORY LOCATIONS THAT
CONTAIN THE PROGRAM O NTO A NORMAL 3.3 DISK, YOU HAVE CRACKED THE PROGRAM.
THIS METHOD IS MOST USEFU L FOR CRACKING THE "SINGLE-SHOT" BOOTING PROGRAMS
SUCH AS APPLE PANIC, RASTER B L ASTER, AND GORGON.  THESE DISKS DON'T CO NTAIN
ANY STANDARD DOS, BUT RATHER THEIR

OWN.  THIS DOS HAS JUST ONE PURPOSE, AND THAT IS TO LOAD THE PROGRAM INTO THE
CO M PUTER, FROM THE DISK, AND START ITS EXE CUTION.  NOW, THIS IS NOT AS
SIMPLE AS I T SOUNDS, AS THE SOFTWARE PROTECTORS ARE NOT DUMB, THEY TRY TO MAKE
IT TOUGH FOR

YOU TO TRACE.  HOWEVER, IT IS NOT IMPOS SIBLE, SINCE THE DISK MUST BOOT UP, AND
S INCE IT MUST HAVE SOME BOOTING PROCESS, THAT IS TRACEABLE.  LET ME TRY AND
SHOW YOU AN EXAMPLE OF HOW TO TRACE A BOOT OF A PROGRAM.LET

ME SHOW YOU HOW TO TRACE APPLE GALAXIAN .  THE FIRST STAGE BOOT STARTS AT
$C600.

IF YOU TURN YOUR APPLE ON, AND TYPE " CALL-151 (RETURN)" AND "C600G (RETURN)",

THE DISK WILL PROCEED TO START AND BOOT THE DISK IN THE DRIVE.	THIS IS BECAUSE
$ C600 CONTAINING THE PROGRAM FOR THE DIS K TO BOOT FIRST.  IF, YOU EXAMINE
THIS P R OGRAM BY TYPING "CALL-151 (RETURN)", AN D "C600LLLLLLL (RETURN)", YOU
WILL SOON C OME ACROSS A JMP $801, NEAR THE END, SP ECIFICALLY, AT $C6F8.  THIS
IS THE LINK T O THE NEXT STAGE OF THE BOOT WHAT WE MUS T DO IS ALLOW THE FIRST
STAGE TO LOAD IN

AT $800, BUT INSTEAD OF LETTING IT RUN (CONTINUE TO BOOT, AND GO TO $800), STOP

THE COMPUTER, AND EXAMINE WHAT IS AT $8 00.  TO DO THIS LETS MOVE $C600 DOWN TO
$ 9600.TYPE "CALL-151 (RETURN)" AND "9600
