No, the code is correct and still all found bytes are accepted by program.

You did understand very well.
I worked with 32bit calculator by cybult.
45 -> ROL 6 -> NEG = EECO
and your example
AF -> NEG -> ROR 6 = 44000001
Seems like there are bugs in this calculator...
Think I have to search another one.
Thanks a lot to you and a new member nicknamed laola, who wrote me a private message.
