@Substring here you go https://www.dropbox.com/s/v68uy2p7xw9vbkh/recalbox-support-20170220181908.tar.gz?dl=0

@Substring currently 4.0 . First attempt was with 4.1, but latest version acts even stranger. Several times after simple restart got all the configs and data wiped out so downgraded to 4.0

@Substring yes. Added few more SNES games. tried them. no good. Screen goes blank right after opening the game.

@Substring unable to launch SNES systems. Well at least with the one that is in default package of Recalbox 4.0

Howdy.
Just made my GBC with PI 2. Turned on AV out for Recalbox. When in menu screen works without any problem, but when trying to launch a game it blinks and goes off. Switched off all smooth functions as per https://github.com/recalbox/recalbox-os/wiki/Connect-your-recalbox-to-a-CRT-with-composite-(EN) , but still no luck. Any suggestions where start to debug ?
