HOW TO UNPROTECT "BRUSHWORK" by West End Film (version 2.43)
|
||
|
||
(1) First, make a copy of the original disk. NEVER, EVER, fool around
|
||
with your only working copy of a program!!!
|
||
|
||
(2) This will take repeated searches with a disk zapper such as Norton.
|
||
Search the file PAINT.EXE. Note that all bytes are in hexadecimal.
|
||
|
||
A. Search for the byte string: A0 83 15 30 E4. Change it to:
|
||
B8 62 00 30 E4
|
||
|
||
-> This forces PAINT to see the letter "b" of its signature, even if
|
||
no "b" is there...
|
||
|
||
B. Search for the byte string: 80 FC 10 1F 58 75 03. Change to:
|
||
80 FC 10 1F 58 90 90
|
||
|
||
-> This causes PAINT to believe that the expected diskette error has
|
||
occurred, even if it hasn't.
|
||
|
||
C. Search for the byte string: B4 3D CD 21 73 03. Change to:
|
||
B8 02 00 90 90 90
|
||
|
||
-> This prevents a diskette check.
|
||
|
||
|
||
D. Search for the byte string: 9C 0E E8 17 00. Change to:
|
||
9C 0E 90 90 90
|
||
|
||
-> This prevents one of the two accesses of the copy-protect tracks.
|
||
|
||
E. Search for the byte string: 9C 0E E8 03 00. Change to:
|
||
9C 0E 90 90 90
|
||
|
||
-> This prevents the second access of the copy-protect tracks.
|
||
|
||
|
||
F. Search for the byte string: 72 02 33 C0 C3. Change to:
|
||
90 90 33 C0 C3
|
||
|
||
|
||
G. Search for the byte string: 3B 06 F9 10 74 1E and change it to:
|
||
3B 06 F9 10 EB 1E
|
||
|
||
-> This makes PAINT think that it has seen the proper graphics board
|
||
signature byte.
|
||
|
||
|
||
BRUSHWORK is now unprotected. Have fun, kids!
|
||
|
||
LET THERE BE SOFTWARE!
