I still have a "book of tricks" which lists a patch for Wizardy I. I'd 
rather not retype it as it was 43 bytes on the boot side and 37 bytes on the 
scenario side!

(BTW, Antoine, I haven't forgotten!)

Hi Vladimir,

Skyfox is an Electronic Arts program protected with their spiralling
scheme, not a tough one, a usual one.

JPL would have told you that:
- Sundog, the frozen legacy (Accolade)
- Hold-Up (Infogrames)
- 18 sector titles
...are a nightmare. Not only because of their format but because they
require a rewrite of the "RWTS". Look what they did to Prince of
Persia from a double-sided 18-sec disk to two double-sided 16-sec
disks.

Mac Arthur's war from SSG is not totally cracked as it is a 4*4 coded
sector protection but with read/write capabilities and the Apple II
memory is full. As more room is required for the 6*2 tables, read is
available on the cracked version but not the write features.

The hardest to crack are those which contain more than one protection
method: cracking a 18-sec or a password protected program is easy
unless you play with the stack, use a mix of on-disk and off-disks
protections.

Microleague baseball appears to be a member of the above community, I
have been requested to crack it but the disk images failed but I'm
lucky, I have the original in my stock of disks.

According to me, compiled language programs are the hardest to crack,
Microprose simulations and Wizardry series, for instance. I don't know
if they have ever been cracked.

There are probably other uncracked titles but I don't know which they
are, and I am curious :-)
