Ghost
Aghost is a recording of a player's performance on a specific track that races on the track alongside them. Ghosts are so-called because players cannot directly interact with them as they race; rather, the player and the ghost will simply pass through one another. They debuted inF-Zero X and have since reappeared in several successive games in the series.
F-Zero X
Ghosts were introduced inF-Zero X as part of the game'sTime Attack mode. In the mode, players could save a ghost of themselves playing for any course that they had completed; furthermore, they could then choose to race against this ghost if they attempted the course again.
Players can only save one ghost on anF-Zero X cartridge; if the player attempts to save any more ghosts, the older ghost will be deleted.
After every successful race in Time Attack, a ghost of the player's performance is recorded, but not saved to the data; ghosts will continually be recorded for as long as the player keeps racing on the track, with a maximum of three ghosts racing against the player as long as they stay on the same course. All of these ghosts will be lost if the player selects another course or quits the Time Attack menu.
In addition, staff ghosts are unlockable by completing the course within ten seconds of that staff member's record.
F-Zero: Maximum Velocity
Ghosts were only featured inF-Zero: Maximum Velocity's newChampionship mode. When first unlocked, the player has access to areplay featuringHot Violet completing the new course; in addition, when the player first plays this course, they can race against a ghost of Hot Violet. If the player can beat the pre-existing ghost of Hot Violet, they can overwrite this data with their own ghost; following this, the player can then race against their own ghost, as well as overwrite any ghosts that can beat the previous ghost.
F-Zero GX

F-Zero GX featured ghosts as part of its Time Attack mode, likeF-Zero X. Functionality was effectively the same between both games, though players could save more than one ghost onto amemory card, with individual ghosts taking up 3 blocks apiece; that said, players can only save one ghost per track.
F-Zero GX notably also added Staff Ghosts to the game; also a part of Time Attack, these ghosts were designed byNintendo staff members, and act as challenge for players to compare themselves to in Time Attack. Staff Ghosts are unlocked when the player finishes a track in Time Attack within ten seconds of the Staff Ghost's time; the player will be awarded ten tickets and the Staff Ghosts can then be purchased in theF-Zero Shop for 25 tickets apiece. Defeating a Staff Ghost rewards the player with 25 tickets.
Outside of the above, a ghost is used in thefinal chapter ofF-Zero GX'sstory mode, as to represent one of the threeCreators that race againstCaptain Falcon.
F-Zero GP Legend
Ghosts returned forF-Zero GP Legend, again being part of theTime Attack mode. Whenever a player clears a track in Time Attack mode, they can save a ghost of their most recent performance, as well as optionally race against them in Time Attack. Like inF-Zero X, the player can only save one ghost at a time to a cartridge.
In Japan, several cards released for thee-Reader add-on featured staff ghosts that could be raced against. After scanning in four cards with two barcodes each, the player could view areplay of these ghosts, then race against them. The ghost can then be saved if so desired, though doing so will overwrite a ghost if the player already has one on the cartridge.
F-Zero Climax
Ghosts returned forF-Zero Climax, again as part of the Time Attack mode. Unlike the previousGame Boy Advance titles, players can now save one ghost per track. Ghosts can also be saved for any custom tracks the player has made.
