Put Roms in arcade folder
You can do a \\retropie\roms  from your computer or do \\retropi IP address\roms

sudo alsactl store  = saves alsa volume settings
alsamixer = brings up the mixer to change the volume
speaker-test -c2  --test=wav -W /usr/share/sounds/alsa -w Front_Center.wav  = plays test file to test the sound

In Sound Settings    Audio card = DEFAULT
                                Audio Device = HEADPHONE   ;if using Headphone jack on Pi if HDMI use HDMI
                                OMX PLAYER Audio Device = Both


Disable the emulator launch script if you keep hitting a button to configure the game rom mame version.
1st. Retropie Setup
2nd. Configuration/ Tools
3rd. Scroll to runcommand
4th. Disable Launch menu
5th. Then exit

Cools up to 550 Sq. and it's very quite,  works great with 1k of solar and a 3K of battery.

In the /home/pi/Documents/camWebServer

To Install: Create directory "Documents" - "camWebServer" , "camWebServer" - "templates" , "camWebServer"- "static"
   in the camWebServer folder put "camera_pi.py" and "appCam.py"
   in the templates folder put "index.html"
   in the static folder put "style.css"

Now, run the python script on the Terminal:

sudo python3 appCam.py

To make it auto start at boot Edit:  /etc/rc.local  Put sudo python3 /home/pi/Documents/camWebServer/appCam.py &
