Okay, short story: I'm trying to make the monorail mod suggested for IC2, but I can't seem to decipher the minecart code due to the constant use of d1-d28. I am getting a basic understanding of the build, but I was hoping someone could give me a brief synopsis/code for the minecart's ability to move. (Powered Minecart would be nice. ^^) I get the code for checking for rails, and vertical movement will be null (Might implement it later if I can get the code to work on horizontal first.), so just the way to get the entity to move across the tracks at the moment would be nice. 
I've already posted this in 2 other forums, both of which got buried deep within and will probably never see the light of an answer.
