@aft3rburn Here's the link to the github instructions I followed:
https://github.com/recalbox/recalbox-os/wiki/Connect-your-recalbox-to-a-CRT-with-composite-(EN)

Hello all! this is my first post.
I have a 2011 Model B, and have been having problems getting the instructions on github to work 100%, or even 75%. I have a yellow composite RCA out jack for video out. When I followed the instructions on github, my Rpi would be really laggy and the sound would be slowed way down and be choppy. I fixed this on my Rpi by changing the config.txt line on the instructions from:
audio_pwm_mode=2 to 1.
I have my Rpi also hooked to a 13" Zenith CRT TV, and while I was in config.txt I disabled overscan and I have a much less "flicker-y" screen! Everything is fine now, life is good!:)

Since this is my first post, please help me in this thread by linking the github instructions on this thread.
Cheers!:)
