Kart Fighter is a pirated Nintendo Game which is complicated to find in the US. It's where there are characters from SMK
Koopa Troopa-Nokonoko
Luigi-Luigi
Toad-Kinopio
Yoshi-Yossy
Mario-Mari
Donkey Kong Jr.-Donkey
Peach-Peach
Bowser-Koopa
When you defeat Bowser, you go to a Mirror Match, then to Bowser, then to Mirror Match. Kart Fighter also used an engine of the NES Pirated Mortal Kombat Games such as Mortal Kombat 3- Special 56 Peoples. The Stages are as follows:
Koopa Troopa and Bowser: Desert
Mario and Luigi: Castle
Toad: Forest
Yoshi: Mushrooms
DK Jr: Palace
Peach: Clouds
I heard that the Mushrooms in Yoshi's stage are from Little Nemo I think. Peach is dressed up like one of Chun-Li's costumes. Each character has 3 special moves, with 3 sound effects for each one. There are 5 difficulty levels to choose from. For a 2-Player game, you must be at the character select screen and the joining player must press right on the D-Pad to be able to play against the other human player. You have a limited amount of continues so when the Continue Screen text changes into different colors, you cannot continue.
