CRACKING ELECTRONIC ARTS' CUT & PASTE
=====================================

THE CURRENT ELECTRONIC ARTS GAMES ALL
USE SIMILAR PROTECTION SCHEMES; IN FACT
THE PROTECTION SCHEMES USED IN CUT &
PASTE, ONE ON ONE, LAST GLADIATOR, AND
PROBABLY HARD HAT MACK ARE ALMOST
EXACTLY THE SAME...

TRACK $21 IS UNUSED ON EA'S PROTECTION,
AND TRACK $22 IS RESERVED FOR A NIBBLE
COUNT. OTHER THAN THE NIBBLE COUNT, EA
USES THEIR OWN SOUPED-UP RWTS, WHICH
LOADS VERY FAST, BUT CAN BE MODIFIED
VERY EASILY TO READ NORMAL DOS 3.3
FORMAT. THE PROCEDURE FOR CUT & PASTE
FOLLOWS:

COPY TRACKS 0 THRU 2 WITH ANY NORMAL
DOS COPY PROGRAM. THESE TRACKS ARE
UNPROTECTED...

THEN CONVERT TRACKS $03 THRU $20 BY
READING FROM THE ORIGINAL WITH THE DATA
MARKER SET TO "D5 BB CF" INSTEAD OF THE
NORMAL "D5 AA AD", AND WRITING TO YOUR
COPY WITH NORMAL RWTS. THIS CAN BE
ACCOMPLISHED BEAUTIFULLY WITH ADVANCED
DEMUFFIN:

]BLOAD ADVANCED DEMUFFIN
]CALL-151
*B858:BB
*B8F1:BB
*B85D:CF
*B8FC:CF
*801G

(CHANGE DEFAULTS TO COPY TRKS $03-$20,
 AND COPY IT..)

THEN MODIFY THE EA'S RWTS TO READ IN
NORMAL DOS (WITH D5 AA AD INSTEAD OF
D5 BB CF) BY EDITING:
TRACK $02, SECTOR $03 -->

   BYTE $47   WAS $BB  CHANGE TO $AA
   BYTE $51   WAS $AD  CHANGE TO $CF

THEN YOU MUST FIND AND DISABLE THE
NIBBLE COUNTS. THE ONLY WAY TO DO THIS
IS TO SEARCH THE DISK FOR CODE THAT
ACCESSES THE DRIVE ("89 C0" ARE GOOD
BYTES TO SEARCH FOR; THEY ARE USED
WHENEVER THE DRIVE IS TURNED ON).
THE FOLLOWING IS WHAT HAS TO BE EDITED:

   TRACK   SECTOR  BYTE   FROM   TO:
   -----   ------  ----   ----   ---
    $01     $0C    $05    $A0    $18
    $01     $0C    $06    $20    $60
    $01     $0C    $68    $20    $18
    $01     $0C    $69    $A2    $60
    $01     $0F    $68    $20    $18
    $01     $0F    $69    $A2    $60
    $01     $0F    $6A    $A1    $EB

THE LAST BYTE, "EB" IS NOT EXECUTED,
BUT IS NEEDED FOR A VALID CHECKSUM TO
BE COMPUTED BY THE ROUTINE. LEAVING OUT
THIS BYTE WILL CAUSE THE PROGRAM TO
BOMB OUT AFTER IT DOES A CHECKSUM ON
ITSELF (THE PROTECTIONISTS HAVE
ANTICIPATED THE TAMPERING WITH THEIR
CODE...)
