I've added few subcategories to also have Genesis on this leaderboard instead of separating both of them. There's few but important differences between the versions so that's why I haven't just let it stay as characteristic but transfered that to a subcategory.
If you have any questions or comments toward that, feel free to comment here.
P.S. Two major differences between the consoles are :
1- Time between end of fight and start of fight are different due of blood disappearing on Genesis that isn't present on SNES.
2- Different damage dealt with the same move on every moves
