Salut @tito http://pastebin.com/ est un site pour copier coller un contenu tu copies colles le texte demandé dans la zone New paste et tu valides par Create new paste et tu copies colle le lien du site. je pense que tu n'as pas tout bien configuré dans les options. L'option Save Game Remap file permet de créer un mapping personnalisé pour un jeu dédié. Malheurseusement cette option n'est pas disponible pour tous les cores , elle est absente notamment de core mame 2003 mais est prévu par la team libretro. Les informations de mapping crée un fichier /recalbox/share/system/.config/retroarch/remap/system/name_game.rmp contenant les informations inputs de chaque joueur : EXEMPLE 1943KAI sous FBA LIBRETRO : /recalbox/share/system/.config/retroarch/remap/FBA Alpha/1943kai.rmp

Pour modifier le mapping : Menu retroarch > hotkey+B Quick Menu > Core inputs options 
Modifier l'attribution des boutons Exemple : j'ai attribué user 1 fire sur le bouton B et les bombs sur le bouton A 
Utiliser le chargement automatique core option : Save ON EXIT > ON User per-game core option > ON Load Rempa file auto > ON 
Sortir du menu retroarch Pour vérifier que l'option est bien activé, sortir du jeu, et relancer le. Le fichier est automatiquement rechargé si il est disponible.
