N64 resulted in the game running at 60 frames per second with thirty machines on screen at the same time, but with little processor power left for graphical detail and music. A Nintendo 64DD expansion, F-Zero X Expansion Kit, was released in Japan as the last 64DD add-on disk for the system. The Expansion Kit added a course editor, a vehicle editor, two new cups, three new machines, and new music. The course editor was the main attraction of this expansion, and was praised for its depth, as it was virtually the same program the game's designers used to make the courses. F-Zero: Maximum Velocity is the series' fourth released installment, but the first incarnation of the franchise for Nintendo's Game Boy handheld. It was the first title developed by first party subsidiary NDcube. This Game Boy Advance (GBA) launch title returned to the SNES F-Zero'''s gameplay with a Mode 7-styled game engine.F-Zero GX was released for the GameCube and developed by Sega's Amusement Vision team, and is the first F-Zero game to feature a story mode. The game was initially titled "F-Zero GC". The arcade counterpart of GX was called F-Zero AX, which was released alongside of its Nintendo GameCube counterpart in mid-2003. The game had three types of arcade cabinets; standard, the "Monster Ride", and the deluxe (which resembled an F-Zero vehicle). F-Zero AX had six original courses and ten original characters. However, by certain difficult means, the six courses and ten characters could be unlocked in F-Zero GX.F-Zero: GP Legend is the second handheld game released for the Game Boy Advance and the second installment featuring a story mode; however, this one is based on the anime series of the same name, introducing a new character named Ryu Suzaku/Rick Wheeler. Unlike the games before it, GP Legend takes place in an alternate continuity set in the 22nd century, instead of following the original continuity set in the 26th century.F-Zero Climax was released in Japan for the Game Boy Advance on October 21, 2004. Like its handheld predecessor, F-Zero: GP Legend, Climax was published by Nintendo and developed by both them and Suzak. This is the first F-Zero game to have a built-in track editor without the need for an expansion or add-on. Custom tracks can be saved to one of thirty slots for future use and they can be exchanged with other players via link cable. If
