I just read about it. I've seen it mentioned before, especially in older DOS games.
If anyone else is interested, you can check it out here:

Paul, could you perhaps give me an idea of where to start if I want to learn to reverse engineer file formats, my programming skills are next to none and the little bit of Spectrum Basic I did is useless when it comes to real applications such as your Level Editor. 
On the topic of compression of the AE CAMs, I would recommend asking at the Xentax forums, in the Graphic Formats section. |
I already asked there long ago and they where no help, I managed to figure it out myself in the end, Huffman is just an example.
The real compression type is a modified MDEC compress type, see here:

Now tell me if you think that seems simple
I'm experimenting with a DLL since I already had some hook code, not looking too likely that its going to work though.
