Le voleur (VIFI Sogiciel, 1982)

[toinet]

#880 - This is the French version of Thief by Datamost. Seven levels to pass to qualify as the master of thieves of the galaxy!

Disk structure
This is a standard 16-sec disk, under DOS 3.3 that cannot be copied with Locksmith. It shows the A error code, meaning that, at least, the address field cannot be read. An analysis with Copy II plus shows that there is no extra track.

Protection type
Locksmith was right. This is a change of epilog markers in the address field:
- D5AA96 DEDEEB (instead of DEAAEB)
- D5AAAD DEAAEB, std for the data field.
The second part is that the epilog value is checked in the DOS 3.3 code. If it finds a different value, it reboots. So, we'll do what we did with the original version of Le voleur: replace the DOS 3.3

How to copy
Boot a DOS 3.3 master disk and
