GoPiGo3 repository inconsistencies

The Raspbian for Robots image on Sourceforge results in a local /home/pj/Dexter repository that is inconsistent with the repository at Github. One difference that I’ve identified is the lack of a ‘Software/NodeJS’ structure in the former. I’ve just cloned the missing bits and it seems to work OK but on reflection I realise there may be underlying C or Python library inconsistencies between new and old code.

How do you recommend I proceed ?
