it is amazing how impossible things can be when you don't know. And usually it is a failing of instruction that causes it.
Reminds me of how many times over the years i have tried to get an Amiga emulator working on my computer. Every time i have ever tried it i am thwarted because the brilliant person who created the emulator doesn't know how to give simple coherent instructions that regular humans can follow. Sometimes i would find one whith what appears to be very good instructions but then when i get into it, suddenly there will be some critical step missing or the old favorite of ambiguity so you don't know if you should do this or that.
