Recalbox works fine with RCA video+audio, but black screen when starting a game...

Hello
First of all, congrats for Recalbox which looks great!

Here is what I've done so far:

• downloaded the latest image (Recalbox 18.07.13) and wrote it to a micro SD card
• removed hdmi_force_hotplug=1 + added hdmi_ignore_hotplug=1 and sdtv_mode=2 in config.txt ; added global.videomode=default in recalbox-boot.conf
• successful boot on my Raspberry Pi 2 connected with RCA / jack 3.5mm to my old TV : the image and sound works
• I can browse the different emulators / games with a USB gamepad

Problem: when I start a game, the screen goes black and nothing happens...

It's kind of strange since it's a totally standard unmodified RPi2, standard recalbox 18.7.13 image, etc... What would be the reason?

Solution: the problem was that it's NOT /boot/recalbox-boot.conf that should modified but this: https://github.com/recalbox/recalbox-os/wiki/recalbox.conf-(EN)
