King's Quest II (Sierra On-Line, 1985)

[toinet]

Romancing the throne. A DHGR game by Sierra... Some people like the series, I do not like it very much.

Protection type
- Disk protection: Nibble count

Disk type
- a standard DOS 3.3 diskette (D5 AA 96, DE AA EB, D5 AA AD, DE AA EB)

How to make a backup copy?
- Copy the disk with your favorite version of Locksmith
Boot the disk, you are led to the text screen: the disk can be copied but it is not working...
- Launch your favorite sector editor
- Search for the HEX string 89C0 (C089 softswitch)
You will find one on track $11, sector $F, the disk protection routine is there...
- Set 11/F/1C to 12 (original value was 01)
- Save the change

You now have your backup disk
