[quote=3524]If you start with the RetroPie SD-card image, first you need to install SNESDev from sources (e.g., via the RetroPie-Setup Script, source-baseed installation, select only SNESDev). The file build.sh is available afterwards.[/quote]

I did use the sd card image but I installed SNESDev via github and not via retropie_setup.sh. If thats what you are saying. I have SNESDev at /home/pi/SNESDev-RPi/ , can I install it from this location or do I need to run the retropie_setup.sh to add the additional files to /home/pi/RetroPie/supplements/SNESDev-Rpi/ ?
