Unprotect for Jack Nicklaus Golf
BE SURE TO BACKUP YOUR PROGRAM DISK BEFORE STARTING AND USE THE
BACK UP FOR THE UNPROTECT.
Modify only the backup copy!!!
First you should rename the file or files
GOLFE.EXE TO GOLFE
GOLFC.EXE TO GOLFC
GOLFT.EXE TO GOLFT
Ex. C>rename golfc.exe golfc
Next Load program into debug...
Ex. C>debug golfc
Then Follow the sample debug session:
-s 0000 ffff e9 84 01 e8 : Search for protection pattern
XXXX:YYYY : The search will return one address.
If more than one is returned
this unprotect may not work.
ZZZZ=YYYY+0009 : Add 9 to the address found
(These numbers are in hex. If you are
unfamiliar with the adding of hex
numbers don't attempt this patch)
-e ZZZZ eb 08 90 90 90 : Edit the contents of the computed
address
Now write the new golfc game back to the disk:
-w <Enter>
Writing XXXX bytes
Then Quit Debug:
-q <Enter>
Now it is time to rename golfc back to golfc.exe
C>ren golfc golfc.exe
Now try to run the new (Hopefully) unprotected version of Jack Nicklaus Golf
C>golfc
