@haricot Cela pourrait être bon?

@haricot thank you for your answer but still it's not clear to me this: in config.txt it is like setting first hdmi_mode=87 and then hdmi_mode=6, right?
So shouldn't the latter declaration (mode 6) disable the first (mode 87)? Or can I set multiple hdmi_modes at once?

@haricot voici un extrait de mon tuto express :

dans config.txt vérifie que tu as bien ces lignes

hdmi_cvt=1920 240 60 1 1 0 0
hdmi_disable_edid=0xa5000080
hdmi_pixel_encoding=2
avoid_safe_mode=1
disable_overscan=0
hdmi_drive=2
hdmi_group=1
hdmi_mode=6
hdmi_force=1

le mode 6 doit être activé pour emulationstation, non le mode 8 ensuite il faut que le mode 87 soit défini dans la résolution de Retroarch comme écrit plus haut...

Ces paramètres ont résolu mon problème, merci beaucoup!!!
Mais ils ont augmenté mes doutes.

Pourquoi spécifier hdmi_cvt=1920 240 60 1 1 0 0 si après vous définissez hdmi_mode=6? il est vrai qu'ils sont deux paramètres équivalents et exclusifs (l'une avec l'autre)?

Merci

@haricot @archimage I have the same issue with my Lindy HDMI > VGA Adapter.
No problems with a "standard" 240p@60hz resolution but I can't set any custom video mode in config.txt.
For the same reason I don't get native games resolution in AdvMAME.
I'll check these settings too... thanks!

@Substring I had this issue also on AdvanceMAME 3.0 with HDMI and Composite, and Andrea fixed it. I suppose he is aware of this strange behavior, and probably he will fix it after the holidays.

Meantime, try to set in advmame.rc the value sync_resample emulation, it worked for me as workaround.

P.S. Speaking of resolution on RPi, we should follow (and also support) this interesting request.

@Substring thank you very much for your advice (and for your constant support) I've yet manually configured my monitor (crt TV) in advmame.rc but it seems an issue related to HDMI > VGA adapter I'm using (I can't even run videomodes in advcfg). I'll check with the GPIO-VGA when I'll receive it.

I'm testing the 3.1 RC and it's great: Andrea fixed many little things, and audio and vsync are now perfect, as the UI.

BTW I've checked both the HDMI > VGA > SCART output and the Composite output and let me say that... to me, lag brought by my Lindy HDMI > VGA is consistent.

Ryuuko no Ken (Art of Fighting) in Composite is much more reactive, I hardly feel the difference with the real CMVS. Can't wait to test the VGA shield on the same aspect.

On the other hand, seeing AdvanceMAME in pure RGB at 240p@60hz (fixed, for now) is impressive.

I smile thinking about how emulation on RPi was different just some time ago. Who knows what the future holds!

@gkralicek2 @ian57 @Substring thank you for your help!
Adding a male - female VGA cable between the HDMI > VGA adapter and Retrocable VGA > SCART fixed it (of course I've also setup config.txt).
Now I have a perfectly clear RGB picture on my good old crt TV.

Unfortunately, it seems that real time resolution switch does not work in AdvanceMAME using the HDMI > VGA adapter (I only get a black screen... l'll write to Andrea).

So I still wait for the GPIO - VGA from Malaysia...

P.S. If someone's interested, I found how to use Unibios in AdvanceMAME.

@gkralicek2 thank you very much for your feedback.
Yes, the USB was connected, but in config.txt I only set hdmi_safe=1.

I'll check with

hdmi_group=1
hdmi_mode=6

Thanks!

Ok guys, I need your help.

RPi3 > HDMI to VGA > OK! (on a LCD monitor)

but

RPi3 > HDMI to VGA > VGA to SCART (from Retrocable.es)

...I get only a black picture.

My crt TV seems to recognize that there is some kind of signal, but I only get a black picture. What I'm doing wrong? :_(

Thanks.

@Scandy That already exists, the rpi2scart ... (A bit expensive the truth)
He thinks that I am alone, I can not launch so many projects at the same time.
I had an idea about this that you are telling me, so that it was not the same as everything I had thought of including in the design a box for the RPi in the form of a console, its connector scart on the back and the DB15 in front, with button of power and reset.
But it's just an idea.

@gkralicek2 If there are, I already have a prototype working.

A board with the same form-factor of RPi, placed on top of it (like a "shield") with female SCART and DB15 controllers... hmmmmmm!
