Skull Fang cheat codes, tricks, hints, and walk throughs.
Proto Fighter
At the begining of the game, there are only four planes available, but after you complete the game in "extra" mode at any level(I think) , press down on control pad when selecting fighter plane, there will be a new black plane.(You must complete the extra mode with one plane, there will only be one proto fighter)
