Unprotecting Broderbund's Ancient Art of War
To unprotect the Ancient Art of War:
1. Make a copy of the original distribution diskette using
the DISKCOPY command. Put your original away, and work
oε thσ copy« Step≤ ▓ t∩ ╢ assumσ tha⌠ ß disδ containing
DEBUG.COM is in drive A:, and your working WAR disk is
in drive B:
2. From the A> prompt, type:
RENAME B:WAR.EXE WAR.SAV
Followed by, of course, hitting the Return key.
3. Now, start up DEBUG with:
DEBUG B:WAR.SAV
4. From the '-' DEBUG prompt, enter:
E8BD8
5. DEBUG will display:
xxxx:8BD8 CD-
The 'xxxx' will vary for your system, but if everything
from the colon (:) onward doesn't look the same, DON'T
continue - either you have another version, or something
is wrong.
Enter 'F8', and hit the space bar. DEBUG will display:
13-
Enter '90', and hit the space bar. DEBUG will display:
73-
Enter 'EB', and hit the space bar, and then Return.
6. Now, from the '-' DEBUG prompt, enter 'W', and hit the
Return key. This will write the file back to disk.
7. Enter 'Q' to leave DEBUG, and from the A> prompt, enter:
RENAME B:WAR.SAV WAR.EXE
and hit the Return key.
Your working copy of WAR will now run, and can, itself, be
backed up using the DOS DISKCOPY or COPY commands.
Note: if you use WAR on a fixed disk, you will not be able
to save a game in progress, due to a small bug - WAR tests the
default disk for the presence of a file named "M", instead of the
selected data disk, the intent being to prevent saving a game on
the same disk as that file. To disable this test, after
completing step 5, patch the following location:
xxxx:3B1D 0B-
replace the '0B' with '31'. This will allow you to save a game
on a floppy disk in the A: drive; Note, however, that this
removes a small margin of safety (if you save a new campain and
a game to the same disk, the game reloader will get confused).
