I am using winuae and I am using rocketlauncher as my emulator in LB. Only some games launch, some games require the rom name in the command line to launch which will be very painful to do for all games, I don’t have a spare week. All games launch fine directly in rocketlauncher, weird. As @polygonslayer suggested maybe LB doesn’t like some of the rom names. Some games launch with the standard command line and some require “romname” after -r as per the above post.
