Ah, I see. Well, if you need to make progress quickly, I don't think Simbrain will be able to help much. 2.0's backprop is based on Snarli, so you are best off using the Snarli library directly:
http://snarli.sourceforge.net/The sourceforge forum does not look active, but Simon Levy, who created it, is generally pretty responsive. I think he may have a newer release which is not on sourceforge yet, but I'm not sure.
Backprop is being rewritten for Simbrain 3.0, but that will not be released for at least 6 months, and probably even later than that, alas.
Too bad about Joone, since so much work went in to developing it and since its focus is backprop. I thought I saw a post somewhere about others picking up with the work on it...
Best,
