      @Scandy @Substring really a great news ... so no need to manage all this resolution stuff with configgen ?

        @ian57 @Substring no need to manage all resolution configs, at least for Arcade. AdvanceMAME now can manage videomodes on Raspberry Pi exactly as it does for Linux and DOS.
        As you can read in my previous posts here, I thought from the beginning that AdvanceMAME would be the perfect "companion" for the findings on this great forum. So I wrote to Andrea some time ago pointing to this thread and various threads on RPi official forums, we started a long conversation by mail and he was so kind to support my stalking buying a Raspberry for the cause. 🙂
        He is still optimizing the code, but yet the real time resolution switch does it work on RPi via HDMI (I'm still waiting for VGA Shield from Aliexpress). But I really hope that Andrea will write by yourself about his gem.
        Resolution switch happens by vcgencmd.

          @Scandy @Substring yep we are already aware of the videomodes changes via vcgencmd command..; we are b*mping the firmware in RB 4.1 only for that :). We use HDMI - VGA converter and some resistors to get a working HDMI 2 Scart cable. After that we get pixel perfect via a "simple" videomode config of the Raspi. For now, we checked the 320x224 video mode. It gives great results.

            Hello everyone,
            I'm a new user of the RGB mod. I have done a VGA666 home made circuit with the modification of the sync lines but i have few questions.
            In fact i have a sync signal issue (few little black marks of the corner of the screen).
            My circuit is made up of two 120 Ohms res for each sync lines (H/V) but i think it is not correct. Let me explain: The GPI pins used fot the Sync lines are GPIO 0 output which means that the 3.3V is pulled up throught a 1.8K Ohms res. So, considering the 75 Ohms of the Csync input (on the TV side) the voltage is far away of the 0.7V expected (may be around 0.13V). What do you think about this?

            Note: Sorry for the english mistakes, i'am french 🙂

                @ian57 @Substring so AdvanceMAME should work out-of-the-(recal)box. 😉

                  had a small overlook at andrea's code, he uses vcgencmd (how else could he have done ? lol).
                  The fact is that AdvMAME is just half way of its full integration in recalbox for now. I will still keep the retroarch track as a primary target

                    What if we use MESS? Which is included in MAME

                      Salut à tous, merci pour ce topic je viens de m'y mettre et ça rend très bien (je n'ai pas encore fait de fichier configuration pour chaque emulateur mais ça claque déjà !)

                      Par contre c'est normal le balayage de l'image même quand j'ai émulationstation d'eteint ? C'est comme si... Y'avait de la neige lol0_1480629780038_DSC_0103.JPG

                      Et je ne sais pas ce que j'ai bien pu faire mais depuis que j'ai bidouillé pour mettre le rgb quand je redémarre la recalbox le raspberry s'éteint mais ne se rallume pas.. Une idée ?

                      Merci !

                        Hi, here I link the schematic of rgb-pi for those who want to make it their own.

                          @Scandy d**n, it won't work yet ...

                          1. advmame is SDL1 not SDL2, which is a REAL pity for pi2
                          2. can't get it to run, it just wants to work on frame buffer, dunno how to change that and I'd hate to use SDL1 (but it looks mandatory to be able to use the keyboard or probably some other inputs)

                            @Substring please take a look to private chat.

                            Cependant: encore un peu de patience... 😉

                              @Substring @ian57 @aTg finally AdvanceMAME 3.0 with official Raspberry Pi support has been released. ;D

                                Salut tous !
                                Juste un petit mot pour vous dire que le cable indiqué par archimage de chez retrocable.es fonctionne et que l'image pète bien sur un trinitron 36cm....
                                J'ai encore des reglages de géométrie à faire dans le menu service de la tele dont je peine à trouver la doc... Mais c'est très encourageant .... Évidement rien à voir avec la composite. Les couleurs sont denses et saturées.
                                Mon image est juste un peu décalée sur la gauche (1cm)
                                Sous E/S, le polices sont trop petites et les thèmes adaptés manquent....
                                Reste aussi à tweaker les résolutions par jeu et là j'avoue gros chantier.
                                Merci à tous pour vos contributions, on va y arriver.
                                Je ne pipe rien aux modelines alors je suis à l'affut de toute info permettant de simplifier le process.....
                                Le seul ennemi ? Le temps !
                                Je continue de passer rapidement ici et sur l'IRC .... À bientôt !

                                  @Scandy great news... will try that ASAP :)... but 1.5 directly to 3.0?

                                    @ian57 I suppose it's because now in AdvanceMAME are included also AdvanceMESS and AdvanceMENU (previous version was at 2.9). I'm curious to read about tests with VGA and SCART. Thank you.

                                      @ian57 dude, need your rpi-(userland|firmware) b*mp PR ! You also need to remove the 2nd advancemame patch from the package

                                        @aTg thank you for sharing this, but I really hope to have the possibility to buy soon a cable assembled by yourself. 🙂
                                        IMHO a "female" SCART would be more practical.

                                          @Scandy The reason that it is a male cable is so that no extra cables are necessary, to move to a female connector should completely redo the circuit since the pins are not all symmetrical, some are crossed.
                                          If there is a lot of interest, I'll do something female.

                                          Well here I finally have revision 2 of the circuit (I already have list 3)
                                          The improvements are very important, the simplification in the soldier is great.

                                            @aTg IMHO telling people to buy a male to female adapter is much better 😛
                                            But the pictures show a very short cable, that could bother some people
