Folks, it is such a shame that I saw this major update to our beloved MC-90V-Simulator only today. On wednesday I will be going on a three week holiday. But when I return, I promise to continue Ichoffs work and try to sort out the problems with the licensing. In the NIS directory, there are three license management DLL's compiled from unobfuscated C# code. The usual decompilers work quite well on that. In the simulator.exe there is a reference to a file "lisens.txt" (probably norwegian spelling). So maybe we can reverse engineer the whole licensing algorithm, instead of patching the binary? Not sure. There is a reference to RSA public-key-algorithms, which, wenn done right, are not hackable without patching the binary.
