Place your ROMS in either
\.emulationstation\roms\megadrive
or
\.emulationstation\roms\genesis
First you need to tell retroarch to use 6 buttons controllers, because the default is to use 3 buttons ones. Launch a megadrive game and go in the retroarch menu (default mapping: select + x). Go in Options -> Core Options and set the two input devices to 6 button pad. Then go back to be root of the menu and choose to save the configuration.
