Bonjour , j'ai trouvé la solution à mon problème , je la poste si jamais quelqu'un a besoin.

Enfaite c'est le mode HD qui se trouve dans les réglages Recablox dans "Option de Jeux".

Il sélectionne automatiquement les émulateurs à utiliser pour les systèmes , donc ne l'ACTIVER PAS si vous voulez pouvoir choisir un émulateur diffèrent pour chaque jeu.

In 8.0.2 all of these games listed worked fine, now most of them didn't start in 8.1

@zing

Thanks for the response, oh yeah I know PPSSPP works better, but I have an arcade machine that has a stick and buttons so I have to rearrange the controls and it works for a lot of games, but some I cannot get it to work right. Retroarc makes it easier from that standpoint. So that is why I wanted to try and add it to my setup.

Recalbox rox!

@zing Merci ! J'ai enfin compris comment ça marchait.

@zacland
Sorry for the delay,- I was on holiday B-)

Are you sure you're running the x64 PC-Version of Recalbox? I verified the option is still there in the latest version 8.1.1: In Mame OSD you should see the list of games, directly under that list is "Configure options" Once selected, a small window opens with several options and "Save configuration" at the bottom

Good luck!

@Ark-0

In uae4arm libretro there is a virtual keyboard and it's qwerty. Which keyboard are you talking about ?

@zing

I think I was just mistaken and the emulator core is MAME 0.230, however it always just shows Mame 2003 Plus as the default core when you go to edit a games information. I'm not sure if this is intentional but that is what confused me. When I actually launch a game and hit tab and go to About Mame it shows version 0.230.

Thanks anyway for your help!

@holmes n'hésites pas à l'overclock à 80 ( en tout cas sur pi4 ) , pour les jeux de voiture c'est le compromis parfait avec l'activation de la résolution ( car cette activation peut ralentir le jeux donc l'overclock équilibre et ajoute même un gap de puissance ) en tout cas pour les jeux de course c'est ultra efficace ce réglage 👍
