Demorelise has never been available for public download.
It is NOT a simple, user-friendly tool and requires a lot of understanding and patient experimentation followed by shouting and much swearing to get it to do what you want.
I understand your point Morfans. I would like to use it in a good way, and I'm not affraid of technical problems. I have found this info in an old QDQ release (all_1949 - very old ): "DemoRelise (...) takes as input two demos of consecutive levels, and relativises the second one with respect to the statistics at the end of the first one. This kind of relativisation will not always be possible; for example, suppose a player uses some ammo in the second demo that they would not have following on from the first. In such cases, DemoRelisation will just produce an error, not an invalid demo. The author was very careful to make sure that DemoRelise produces correct demos, and it gives warnings about anything that is concerned may cause a problem.". Thats what I would likie to use it for. If someone is willing to send me the file(s) this is my email poco2s@o2.pl. Thanks in advance
