Has anyone setup Altirra with Retorarch in launchbox? I'm trying to launch a specific game using an specific input map Centipede. I rightclick on the game and edit meta data and under emulation I'm trying to set a command-line flag to use a custom input mapping that I setup in Altirra. Any info would be appreciated. Thank you

How can I have the game open in Altirra when selecting it from launchbox/bigbox? When I select a game, it runs Altirra but I have to select boot image from the file menu and navigate to a rom and load it. Any ideas? -RB
