Norfair

Norfair is an area located deep in the underground caverns of planet Zebes that has many volcanic based enemies and features, such as a number of superheated rooms that Samus will take damage from if she hasn't yet acquired the Varia Suit, as well as the many pools of magma that Samus can't traverse unless she has the Gravity suit. The deepest part of Norfair is incredible dangerous, as it is home to the lair where Ridley resides.

In M.U.G.E.N, Norfair has been made three times, twice by BaganSmashBros and once by EXShadow; BaganSmashBros' versions use assets from the Norfair stage as it appears in Super Smash Bros. Brawl, while EXShadow's version uses assets from the Omega form of the Norfair stage as it appears in Super Smash Bros. for Wii U.

EXShadow's version
EXShadow's version of Norfair uses graphical assets of Norfair's Omega form stage taken from Super Smash Bros. for Wii U, to the point where the only noticeable difference between the stage and its Super Smash Bros. series incarnation being the platform slowly moving up and down to give off the impression that it is hovering; the stage's camera is always zoomed out to a certain distance by default and only zooms out a tiny bit further should the combatants place enough distance between themselves. Several tricks have been employed to try and emulate some of M.U.G.E.N 1.1's features without actually using said features, one of those tricks is the RGB method that's used for the sprites of the stage platform and the magma flowing below it, so as to get around the 256 colour per sprite limitation present in older versions of M.U.G.E.N; another trick is the anti-alias effect on the stage platform, which is actually a single sprite that uses subtractive transparency being layered over the top of the main platform sprites. The stage technically works in M.U.G.E.N 1.0, though certain issues show that it was probably only intended to be used for M.U.G.E.N 1.1, such as the combatants being too high up and the stage platform's hovering effect being de-synchronised with that of the characters standing on it.
