Speedlock D7 1989 completely documented

[Joseman]

Hi all

I've been documenting the diabolic Speedlock D7 1989 Version.

It was horrible, tedious, almost headaches while documenting it, but it fell down at last!!

among other things, 50 decrypts, 13 checks for  Multiface hardware.

Seeing how this works now, i've a doubt with this protection scheme

The speedlock disk version was broken back in the day it was active?

It seems that the crack availables are based on tape version or i'm wrong?

the comments of the loader are in spanish (sorry), but anyway here it is

Sorry, I deleted temporarily the loader, looking at the Hammerfist loader I realised that there are mistakes on the comments.

I'll upload again soon.

Hi

I uploaded the loader again

I corrected and aggregated new information.

Depending of the game and the disc format, the loader uses different routines.
