I am not sure I follow your point.
When importing the games, I chose the "copy files to platform folder" option, instead of "moving file ...", or "leaving files ...". Since the platform name is "Sega Megadrive", I would expect the roms to be copied in the "Games\Sega Megadrive" folder. Instead, it copied them to the "Sega Genesis" folder, despite showing the "Sega Megadrive" folder in the plaftorm config screen. Why did it copy them to the Genesis folder instead of the Megadrive folder? It is NOT what I told LB. And even if there was a logic to it, that I am missing, why does it say that the platform's roms folder is Megadrive when LB itself used the Geneis folder?
