DEMUFFIN  AND DEMUFFIN PLUS IS ONE  OF
THE   EASIEST  AND  BEST  METHODS  FOR
CRACKING THOSE DISCS WHICH HAVE A  DOS
(AS  OPPOSED TO A 'QUICK-LOADER') THIS
LETTER WILL HELP YOU DETERMINE IF  THE
DISC   YOU   WANT  TO  CRACK  CAN   BE
DEMUFFINED,  AND  IF SO,  HOW  TO  USE
DEMUFFIN TO CRACK IT.
IF YOU GET A BASIC PROMPT,  EVEN ONCE,
DEMUFFIN WILL WORK (ALTHOUGH YOU STILL
WILL OFTEN HAVE TO REWRITE PORTIONS OF
SOME OF THE PROGRAMS YOU TRANSFER,  OR
RECOVER BITS OF ASSEMBLY PROGRAMS THAT
ARE  ON THE ORIGINAL,  BUT NOT IN  THE
DIRECTORY...REMEMBER,  THE PEOPLE THAT
WRITE  GOOD  PROGRAMS ARE NOT  STUPID,
THEY  WILL USE EVERY TRICK TO TRY  AND
MAKE CRACKING THEIR PROGRAM IMPOSSIBLE
...YOUR  JOB AS A CRACKER IS  NO  EASY
ONE!!!...A  TRULY  PROFICIENT  CRACKER
MUST  BE FLUENT IN ASSEMBLY LANGUAGE).
IF YOU CAN GET A CATALOG BY ANY METHOD
FROM THE ORIGINAL, DEMUFFIN WILL WORK.
ONCE YOU HAVE DETERMINED DEMUFFIN WILL
WORK,  BUT BEFORE YOU USE IT, YOU MUST
UNDERSTAND WHAT IT IS...  MUFFIN IS AN
ASSEMBLY  PROGRAM WHICH READS ONE DISC
FORMAT AND THEN WRITES ANOTHER.  APPLE
DESIGNED MUFFIN TO READ 13 SECTOR  AND
WRITE 16 SECTOR.  THEN SOME PROGRAMMER
DECIDED  THAT  IT MIGHT BE  USEFUL  TO
READ  16 SECTOR AND WRITE 13 SECTOR...
THUS NIFFUM WAS BORN.  NOW SOME CLEVER
PIRATE THOUGHT 'WHY NOT READ WITH  THE
DOS THAT IS ALREADY IN THE MACHINE AND
WRITE  WITH 13 SECTOR'.  THIS  PROGRAM
(WHICH  WE KNOW AS DEMUFFIN) TAKES THE
DOS  WHICH  YOU  LOADED  IN  WHEN  YOU
BOOTED THE ORIGINAL AND USES THIS RWTS
TO READ;  DEMUFFIN HAS 13 SECTOR  RWTS
BUILT IN AND USES THIS TO WRITE OUT IN
STANDARD  13 SECTOR FORMAT.   DEMUFFIN
PLUS DOES EXACTLY THE SAME THING, ONLY
ITS  INTERNAL  RWTS WRITES OUT  IN  16
SECTOR.
NOW THAT YOU KNOW A LITTLE ABOUT  WHAT
DEMUFFIN  IS...ON TO THE NITTY GRITTY.
NOTE  THAT ALL REFERENCES TO  DEMUFFIN
APPLY   TO  DEMUFFIN  PLUS  AS   WELL;
REMEMBER  THAT  BOTH PROGRAMS  DO  THE
SAME  THING,  DEMUFFIN OUTPUTS  IN  13
SECTOR  WHILE DEMUFFIN PLUS OUTPUTS IN
16 SECTOR.
THE  'SECRET'  TO  USING  DEMUFFIN  IS
REMEMBERING  THAT  IT IS  AN  ASSEMBLY
PROGRAM  DESIGNED  TO  OPERATE  AT   A
SPECIFIC LOCATION IN MEMORY ($803). IF
YOU  LOAD IT IN SOMEWHERE ELSE AND TRY
TO RUN IT,  IT WON'T WORK.  THIS WOULD
NOT  EVEN  REQUIRE  MENTIONING  EXCEPT
THAT THE AREA AT $800 IS DESTROYED  BY
A  BOOT!   KEEP IN MIND THAT  DEMUFFIN
MUST BE IN MEMORY BEFORE YOU BOOT THAT
PROTECTED DISC YOU'RE TRYING TO CRACK.
ONCE  YOU'VE BOOTED THE PROTECTED DISC
YOU WILL BE OPERATING UNDER THEIR  DOS
AND  YOU WILL NOT BE ABLE TO READ  THE
DISC THAT CONTAINS DEMUFFIN (YOUR DISC
HAS   STANDARD   DOS...REMEMBER?)...SO
WHAT  ARE  WE  TO DO?  THERE  ARE  TWO
CHOICES:  ONE  IS TO USE TAPE  (UGH!);
THE OTHER IS TO FIRST LOAD DEMUFFIN IN
SOMEWHERE THAT THE BOOT WON'T  DESTROY
IT.  THIS IS THE METHOD I RECOMMEND
FIRST BOOT YOUR DOS AND BLOAD DEMUFFIN
AT   $6000 [I CHOSE $6000...THERE  ARE
MANY 'CORRECT LOCATIONS']
SECOND  BOOT THE ORIGINAL (PGM  TO  BE
CRACKED)   AND  RESET  AFTER  DOS  HAS
LOADED  AND  THE  FIRST  PROGRAM   HAS
STARTED  TO LOAD IN.  PROPER  RESETING
DEPENDS  ON MANY THINGS SUCH AS  WHICH
MONITOR  YOU HAVE AND HOW AND WHEN THE
ORIGINAL  SETS  YOUR RESET  VECTOR  AT
$3F2-$3F3.    I  WILL  DISCUSS  PROPER
RESET METHODS IN THE NEXT LETTER.
THIRD GET INTO THE MONITOR (CALL  -151
OR  RESET  ON  THE F8  ROM)  AND  TYPE
803<6000.8000M  N 803G      THIS  WILL
MOVE  DEMUFFIN  BACK WHERE IT  BELONGS
AND START IT RUNNING.
FOURTH FOLLOW THE INSTRUCTIONS...
