Unprotect for RamPage (IBM PC)
BE SURE TO BACKUP YOUR RAMPAGE DISK BEFORE STARTING AND USE THE
BACK UP FOR THE UNPROTECT.
Modify only the backup copy!!!
First you should rename the file or files
RAMPAGE.EXE TO RAMPAGE
Ex. C>rename rampage.exe rampage
Next Load program into debug...
Ex. C>debug rampage
Then Follow the sample debug session:
-s 0000 ffff b8 ef 04 50 33 : Search for first protection pattern
XXXX:YYYY : The search will return one address.
If more than one is returned
this unprotect may not work.
ZZZZ=YYYY+0007H : Add 7 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 03 90 90 90 : Edit the contents of the computed
address
ZZZZ=YYYY+0012H : Add 12H 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 0C : Edit the contents of the computed
address
Now write the new rampage game back to the disk:
-w <Enter>
Writing XXXX bytes
Then Quit Debug:
-q <Enter>
Now it is time to rename rampage back to rampage.exe
C>ren rampage rampage.exe
Now try to run the new (Hopefully) unprotected version of RamPage
C>rampage
