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
