Sin: People bring their Gamecube, hook them up… (I don’t know how yet… maybe a new accesory).
So 4 Gamecubes, 4 TVs, 4 F-Zero GX and 16 controllers connected together would allow people to play 16 people to race on VS mode.
As for the parts:
Base : Fire Wolf
Cockpit : Bright Spear
Boosters: Titan -G4
Emblem : The Orange Fire one, x4
