Ok, When i played the game on pc using MAME 0.154 it says:
“The selected game is missing one or more required Rom or CHD images”
but in RetroPie it display black screen has the text below on it & quite the game.
ng on HDMI with explicit setting (CEA mode 4)
“knightsofValour” not supported
ng on HDMI with preferred setting
Can you tell me how to change romset for mame games. please ?!
