You can access the Retroarch GUI by adding the following to your retroarch.cfg:

input_enable_hotkey_btn = 
input_menu_toggle_btn = 

You can also create specific controls for Picodrive by placing another retroarch.cfg in /home/pi/RetroPie/configs/megadrive/ which will override the default retroarch.cfg
