Keen: Modding

Since I'm using 32-patch level patch for CK1, I want to add extra statue messages. How is this possible? Because I remember - as if I saw a Keen 1 mod containing extra statue messages - but I don't know how to do that.

Help.

I wrote a program called STARTEXT that lets you write Yorp messages for 32 levels. Its keenwiki page is here: http://www.shikadi.net/keenwiki/Startext
