Restarting service after changing config/emulation isn't killing old services

At boot:

You need to use

cd /home/pi/temp/sdl/escparser
./retroprinter-restart.sh

Open to ideas how to make the service restart run this!!

OK that seems to work, thanks! I don't know much about service startup scripts, sorry!

I just realised the problem is that I did not add a restart section to the init.d script!

/etc/init.d/retroprinter should now read:
