@mitu FANTASTIC !!!!
Everythings working with lr-fmsx!!! I focused to much on Lr-BlueMSX. For Lr-BlueMSX, It's only playable with keyboard . The joypad working only for Coleco. Not enough gamepad buttons are associated with basics keyboard fonctions. They should enable the "RetroPad Keyboard Map - Joypad - Awaiting description" option in Control menu in RetroArch for MSX.
