[QUOTE="catflap, post: 77371, member: 183191"] That's a bit negative, isn't it? Won't work? Why not - the interface to the card is known and it is well-known (and the processor on the card is known), so with the SW for the card everything is predictable. I.e., for any given input it should only be a matter of just sendning it to an emulator and we should get the appropriate result. And since the speed of a normal computer is way higher than for a smart card, the answer should be ready in time even if the card processor is emulated. I'm sure there are emulators for the processor already (this is normally made available for SW developers), so with a few interface additions and the SW for M-II.exe... If this is not possible, please also say why. I can think of a few difficulties, such as the code being encrypted inside the file, but in that case we also have the loader inside the file and can decrypt using that. (In worst case, - but this shouldn't be needed - it should be possible for someone to actually flash an M-II card and then read back the info.) [/QUOTE]
