I couldn't find said example (sorry), but I did find one of his other examples of abusing the assembler:

You won't believe me unless you try it for yourself, but ... download xkas v06 here:

Then download the above boredom.asm. And now run the following on the command-line:

    touch boredom.sfc
    xkas boredom.asm boredom.sfc

Note again that this is a cross-assembler to produce code for the Super Nintendo. Yet you will be greeted by a fully-playable game of Snake in the terminal window. No, I am not kidding. (The black hats here can probably guess what's going on.) For those who won't/can't try it out: http://i.imgur.com/LTSAHw1.png
