I forgot he was the same person who did that! I was somewhat obsessed with it earlier this year. I had found a version you can type into BASIC that pokes it into a block of memory and jumps to it, since I have access to a C64 at a hackerspace that doesn't have a floppy drive, so I've run it at least once on real hardware. (I have a new C64 Ultimate on the way as well.)
