There exists two extended, solo versions of the Emerald Hill Zonestage in Super Smash Flash, that appear on Race to the Finish. Both function as the sixth level of both Classic and Adventure mode. Players must traverse these stages comprised of two large platforms divided by a massive gap filled with a slapdash arrangement of smaller platforms. The large platform on the far left marks the starting point, while the large platform on the far right contains the finishing platform. throughout the entire stage, the player is constantly harassed by swarms of Buzzers, robotic-bee enemies from Sonic the Hedgehog 2, that serve mostly to intercept players, robbing them of their jumps and forcing them into the abyss below.
There are two different versions of this stage. The Classic mode iteration is relatively short and follows a straight path, while the Adventure mode iteration is much harder, having a longer length, more enemies, and less platforms overall. The Adventure mode version is also on a steep incline, forcing the player to make more precise jumps while punishing them harder for any mistakes.
Emerald Hill Zone is the name of the first level in the Sega Mega Drive/Genesis Sonic the Hedgehog 2. The stage carries a basic design, but it is mostly comprised by tilesets from the original game.
