I don't know German, but I have been reverse engineering Viaccess lately (targeting Fransat and TNTSAT) with some moderate success.
I wanted to share my CAM files since you have such a nice section here (which I've never seen in any other forum board!).
I also have photos but I don't know how to upload them since the forum says they're too big ??
I.'m still working on exploiting the CAM to get access to RAM. The progress I made is with STB Firmware. Some implement a portion of the CAM in pure software, but some interesting details are missing that are present in the CAM, which is why I bought a couple to see how to break them.
