I know there aren't many ppl using this, but for those that do want to use SSMAPA in Juicy 3.1, it IS possible using the workaround found here:

You just have to unsign the two files listed in that workaround and replace them after running SSMAPA.
Good news for ppl who want to remap the TF home screen buttons on Juicy 3.1. I can confirm that it does work.
