Maze Generation In Thirteen Bytes

Posted by Trixter on December 17, 2012

Update 1/7/2013: herm1t further smashed the record, down to 11 bytes!

Update 1/7/2013 @ 18:00: Peter bounces back and reclaims the record with 10 bytes! It kind-of breaks my target platform (uses an undocumented opcode that only works on Intel processors) but hey, a record’s a record! I’ve updated the article below.

In the past, when I’ve had a democoding breakthrough, I kept quiet and either used my discovery in a production, or just bragged to my demoscene friends privately.  However, my opportunities to achieve democoding “world firsts” are just about gone, and size coding compos seem to be dead, so I’ve decided to just write a blog post about what I’ve done instead: I’ve written a maze generator in only 13 bytes of x86 machine code.
