Hey! Just submitted a Mega Drive run. I guess the people over at Sega thought the game was too hard so they call the default difficulty setting "Hard" and added easier difficulties "Medium" and "Easy". These should be added as their own categories obviously (you get more lives to start with, it's easier to get extra lives with points and the enemies die with fewer hits).

My run was done on easy difficulty because it's the fastest and most consistent difficulty to run. So we could start out with just renaming the Mega Drive / Genesis category Single Segment (easy difficulty) or something and then add other categories if people start running the other difficulties too.
