UNPROTECT FOR F-19 STEALTH FIGHTER (MICROPROSE SIMULATION SOFTWARE)
First, make a copy of DISK A (the master disk) using DOS DISKCOPY program.
Put the original away in a safe place.
Put a formatted disk in drive B: and copy DEBUG.COM (supplied with your DOS
disk), F19ZAP.BAT, AND F19ZAP.DAT [and START.DAT, see below] to that disk.
Put the copy of DISK A in drive A:
Type "B:F19ZAP" (omit the quote marks).
This will unprotect the version of SU.EXE that's dated 10-15-88, but
probably won't work for other versions.
Your disk is now unprotected. Enjoy!

Why did I waste a few hours of my time creating this unprotect???
Microprose, in their less than infinite wisdom, states in their manual:
"Responding to past critiques, we've changed our schemes, making them
unobtrusive."
If their future protection systems get any less obtrusive, they'll start
checking your blood type and fingerprints before running!
With the older copy protection systems (i.e. in GUNSHIP), you would run an
install program which would stick some hidden files on your hard disk. After
that, you'd just load the game, it would check for the hidden files, and
you're off and running. With this new & improved "unobtrusive" system, you
are tied to your one "key disk". Even though you may have a super-duper
386 machine with a 300 meg hard drive, you still must have the holy floppy
in drive A: or B: to load the game (and then waste more time trying to
identify a fuzzy aircraft picture). If it gets lost or if your dog eats it,
you're screwed. For me, this usually entails digging through piles of stuff
on my computer desk, hunting for the damn floppy. After you've broken the
scheme on your master disk, the floppy is no longer needed to load the game.
Now I just have to find the f'ing manual to go thru the "Aircraft ID Quiz".
Such is life!

Thanks for the unprotect, Jeff. I am adding to your files to include a patch
for the "Aircraft ID Quiz". The quiz will still show up but you can select
any ID and they are all the "Correct Identification".
I have added to the F19ZAP.BAT file and added the file START.DAT to patch
START.EXE.
I have also added the file F19ZAPHD.BAT for use with a hard drive. In order
to use this patch make sure a copy of SU.EXE and START.EXE from your F19 disk
are in the current directory along with the BAT and DAT files included within
this archive. The patch utilizes DEBUG.COM so this must also be in the cur-
rent directory or in your PATH. Now just type F19ZAPHD to run the batch file
and the patches will take place. You can now copy these files (NOT TO YOUR
ORIGINAL) along with the other F19 files to the media of your choice.
