Daegann's Character Generator sort of does it.
http://forums.dumpshock.com/index.php?show...995#entry321725It tracks both karma and BP for stuff you add to the character. Lots of cavets though. After you build the character you'd make a note of the karma rating at that point as the zero starting point. You'd also have to make sure you handled equipment additions outside of the program because it is constantly tracking the cost of that and adding 1BP/2Karma for every 5,000
of equipment. This gets very screwy when you start adding 'ware to your character during play because you have to take the cost of the 'ware/5000 into account and change the zero starting point for the karma.
Karma Character BuildsYou shouldn't really try to use that program for a Karma build like BeCKS because it uses 1BP for 1 Karma for metahuman types. There has only been one person that I know of that wrote out and posted a system that is similar to BeCKS, and when they did that they also changed the karma costs for improving Attributes and Skills so it makes it of little use unless you want to deviate from the rules that much.
It is going to take a while for there to be enough experience with SR4 to properly design a BeCKS equivalent, and frankly very little need for it until some more books come out. The imbalance between BP and karma in SR4 isn't nearly as bad as SR3, character creation has some extra flexibility, and there is very little currently available outside character generation that is not addressed inside character generation. Those are the key areas that BeCKS was aimed at.
