Bonjour à tous,
C'est un sujet récurent mais après avoir bien cherché je n'ai pas de solution :
Je possède un écran CRT sur lequel j'ai branché mon PI 3 model B par la sortie composite.
J'ai réalisé le câble moi-même en m'assurant de bien souder les fils aux bons connecteurs en suivant le tuto https://github.com/recalbox/recalbox-os/wiki/Connectez-votre-recalbox-à-un-CRT-avec-composite--(FR)
J'ai bien modifié le config.txt et recalbox.conf par le biais de winscp en autorisant l'écriture de la partition.
J'ai bien l'image (bien qu'un peu tronquée mais je verrai ça plus tard) quand je démarre le Raspberry, je peux naviguer dans les menus et les listes de roms... mais dès que je lance un jeux sur n'importe quelle console je perds l'image (mais le son fonctionne).
Je me doute bien qu'il doit y avoir une petite erreur dans ma conf mais je ne trouve pas.

Ci-après mon config.txt et recalbox.conf tels que je les ai configurés. Y a-t-il une erreur ?
Merci pour votre aide

uncomment if you get no picture on HDMI for a default "safe" mode

#hdmi_safe=1

disable_overscan=1

uncomment to force a specific HDMI mode (this will force VGA)

#hdmi_group=1
#hdmi_mode=1

comment to get jack audio

#hdmi_drive=2

Using /etc/modules is deprecated and no longer supported on 4.4 kernel

So manually enable audio

dtparam=audio=on

#config_hdmi_boost=0

force hdmi while the tv can take time before sending the signal on the hdmi output

#hdmi_force_hotplug=1

uncomment for composite PAL

sdtv_mode=2
hdmi_ignore_hotplug=1

uncomment for lirc-rpi

#dtoverlay=lirc-rpi

if you plug your tv at the same time as your rpi and that the rpi switches from the hdmi or give a low resolution because tv had no enough time to initialize it

boot_delay=3

uncomment if you don't want the rainbow at startup

disable_splash=1

default CEC name

cec_osd_name=recalbox

Overclock

gpu_mem_256=128
gpu_mem_512=256
gpu_mem_1024=512

avoid_safe_mode=1

kernel=zImage
overscan_scale=1

select your mode from the command : tvservice -m [MODE]

CEA 5 HDMI : 1920x1080 @ 60Hz 16:9, clock:74MHz interlaced

CEA 4 HDMI : 1280x720 @ 60Hz 16:9, clock:74MHz progressive

use 'default' for using the default resolution

(string)

global.videomode=default

Shader set

Automatically select shaders for all systems

## (none, retro, scanlines)
global.shaderset=none

Once enabled, your screen will be cropped, and you will have a pixel perfect image (0,1)

global.integerscale=0

Set gpslp shader for all emulators (prefer shadersets above). Absolute path (string)

global.shaders=

Set ratio for all emulators (auto,4/3,16/9,16/10,custom)

global.ratio=auto

Set smooth for all emulators (0,1)

global.smooth=0

If you don't have issues with your controllers, let auto

global.inputdriver=auto

If you do not want recalboxOS to generate the configuration for all emulators (string)

;global.configfile=/path/to/my/configfile.cfg

------------ I - EMULATORS CHOICES -----------

You can override the global configuration here

Here is the snes example

;snes.videomode=CEA 4 HDMI
snes.core=snes9x_next
;snes.shaders=/recalbox/share/shaders/shaders_glsl/mysnesshader.gplsp
;snes.ratio=16/9
;snes.smooth=0
;snes.rewind=1
;snes.autosave=0
;snes.emulator=libretro
;snes.integerscale=0

If you do not want recalboxOS to generate the configuration for the emulator :

;snes.configfile=/path/to/my/configfile.cfg

Default cores for RPi3

snes.core=snes9x_next
gba.core=mgba
mame.core=mame078
nes.core=fceunext

NeoGeo emulator

You can use pifba or a libretro core (fba2x,libretro)

neogeo.emulator=libretro

If you set libretro as neogeo.emulator, the line below sets the retroarch core (fba,imame4all)

neogeo.core=fba

N64 emulator is configured to display a screen with a 640x480 resolution (native n64 resolution)

So you must use one of these video modes (DMT 4 HDMI,CEA 1 HDMI).

If your screen is not compatible with one of these video modes, please check the recalbox's wiki.

#n64.videomode=DMT 4 HDMI

If you are using a CRT screen, please change the setting above with this one :

n64.videomode=default

Dreamcast emulator

Like N64, such a CPU intensive emulator needs a small resolution

Consider DMT 4 HDMI (640480) or DMT 9 HDMI (800600). If you have a black screen on dreamcast, try DMT 9 HDMI here

dreamcast.videomode=DMT 4 HDMI
