job will be to trade the protection code for the valid program
code. Believe it or not, this is the easy part.
4) Make sure you have a write protect on your ORIGINAL and that the
original is in the disk drive. Start the program working by
typing GO B000 and hit RETURN. The drive should start up and, a
few moments later, the screen should change colors. At this
point, reset your computer and turn the disk drive off and on
again. Re-SYS the monitor back in (SYS 32768) and again turn off
BASIC as described above. Disassemble code at $B000 (D B000)
again and note that the code has, indeed, changed. The encrypted
code has been replaced with loader code. All that's left now is
to save the file back to the backup.
Working with your backup:
5) Checking the disk log provides the start and ending addresses
($B000-$B1A2) to the LOADER file. When saving it, be sure to add
one byte to the end address <> S "@0:LOADER",08,B000,B1A3 <>.
Your backup is now protection free and may be file copied. One
small problem remains. That is the directory. The repair for this
is simple. Using the Name/Id Changer on the utility disk, change
the disk name AND the ID number. You must use five figures when
changing the ID number. For example, you could name the disk
IMPOSSIBLE and renumber it IM 2A. When this is completed, your
break will be complete and even the directory can be viewed.

Procedure:
Loading the original produces a rattle free load, and an error
scan shows a number twenty error on track 16, sector 20 and track
15, sector 20. A backup made with the C-64 Fast Copier provides a
non-working backup. Nybble utilities are capable of providing a
backup. Before starting to work on this title, please make a
backup and do a disk log (print-out is best).
Working with your original:
1) Turn off your computer and insert the reset assembly into the
cartridge port. Turn your computer on again. From your utility
disk, load the $8000 monitor <> LOAD "32768" ,8,1 <>. Now, type
NEW, and hit RETURN. When loading the boot file on this disk, it
will autoboot and continue running. In order to inspect it,
here's a trick to use. We're going to load the autoboot into
BASIC memory for the purposes of inspection. Load the boot file
