Unprotect for Bubble Ghost
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
BUBBLE.EXE TO BUBBLE
Ex. C>rename bubble.exe bubble
Next Load program into debug...
Ex. C>debug bubble
Then Follow the sample debug session:
-s 0000 ffff 8a 77 05 b2 : Search for protection pattern
XXXX:YYYY : The search will return one address.
If more than one is returned
this unprotect may not work.
-e XXXX:ZZZZ e9 16 01 : Edit the contents of the computed
address
Now write the new bubble game back to the disk:
-w <Enter>
Writing XXXX bytes
Then Quit Debug:
-q <Enter>
Now it is time to rename bubble back to bubble.exe
C>ren bubble bubble.exe
Now try to run the new (Hopefully) unprotected version of Bubble Ghost
C>bubble
