Ha! sorry, just a stroll down memory lane;
This is a really old bot and to be honest I can't remember what PY actually modded this bot for (other than to make it work following a program change), some of the early (PY) changes were quite drastic when you looked at the effect they had on the existing bots.
It does look like it was designed as a tie bot originally, *.refeye 12 != was to stop it tieing to it's babies as you can see from the *.trefeye 12 = later in the DNA and I do remember that wasn't a change PY made to the modded bots. It was to prevent a loop that bots could get stuck in at one point in the evolution of DB though.
There is a good chance it isn't feeding through the tie anymore as well.
As competition for another bot I doubt this bot is really worth bothering with anymore.
