soo orignally i was trying to make a adder based off my minecraft one where it precalculates the carries but somehow i ended up with this, Insipred by Sandlizards filt guide simply because i just went "dam thats cool"
Look for the "How do I start learning about FILT tech?" thread in on the forum, it uses some newer FILT related features like deserialization to create FILT ROM and RAM.
