Mickey Mania for the Genesis is the best version. SNES is kind of janky in places. The Sega CD version risks copyright over it's improved more Disney sounding music, and the PSX version has "find all this crap before you can finish a level." So this is the definitive version of a stellar platformer of the era. Main weaknesses being, difficulty plus limited continues. If this had unlimited continues like Ninja Gaiden, I'd give it an A.
