Prototype Info

Hidden Password Screen

There is a hidden password function brought about by pressing L, R, Start, R, L, Select at the machine selection screen in Grand Prix mode. This password unlocks the Jet Vermillion early. The two other methods being completing master class with every machine in every cup or racing the championship circuit 255 times. The password is dependent on the name the player chooses for the file select screen. There is a 3rd party password generator to obtain the correct password. Once the Jet Vermillion is unlocked, the screen becomes inaccessible for that save, unless the save is deleted and restarted.

Silence

Through hex editing or patch codes, it's possible to play the multiplayer-exclusive track "Silence - Open Circuit" in Single Player mode.

By freezing RAM address 3000C01 at 29 and opening the Pawn Cup in Training Mode, one can run a Time Trial on Silence. It always uses the Best Lap time of Tenth Zone East I (Snake Circuit) as its Best Time. Completing a Time Trial on Silence before setting any records on Tenth Zone East I will result in the Best Lap for the latter being set to 59"99.

It is also possible to view a Rankings screen for Silence by freezing RAM address 03002CA8 at 29 and viewing the Pawn Cup Rankings. However, no records of any kind can ever be made for the track. The game will display the track's name ("Open Circuit") and displays the correct horizon image, but it can't call the right location name ("Silence") and, instead, displays random tiles. As the track doesn't belong to a Cup, it also places the track name in the wrong place.

Curiously, Silence doesn't seem to have an associated music track, resulting in the background music being appropriately silent. However, this could be intentional, as the course can only be played in the game's Single-Pak mode which, due to the size limits of the Game Boy Advance's boot RAM, only transfers what's necessary to play a proper game with sound effects. F-Zero GP Legend and F-Zero Climax's Single-Pak multiplay mode are also without music and use exclusive Single-Pak courses. However, the locations for those courses - Big Blue and Fire Field, respectively - also appear during the Single Player Cups and the unique courses, themselves, will play the appropriate music if they're forced into a Single Player mode in those games.

Unused Music

There are four music tracks which go completely unused in this game.

A theme that sounds vaguely reminiscent of the original game's title theme. Used for the title screen of at least one prototype build of the game.

A jazzy little ditty. It slightly resembles the race results tune of the final game.

An inspirational song that could either fit as a track theme or possibly an ending tune. Used for "The Ancient Aqua" venue of at least one prototype build of the game.

A somewhat nervy theme that would sound right at home in any twitchy race course.

The last tune above is located just before Empyrean Colony's theme, whereas the other three are back behind a handful of sound effects at the very beginning of the ROM's audio data.

Debug Menus

Parts of a debug menu still exist in the game, but the code that would have handled entering and exiting them appears to have been removed from all versions. One can still cheat to access them, however.

Note that, while most of the values displayed by the debug menus are editable, changing vehicle stats has no effect. That happens because the debug menu only edits a copy of the vehicle stats. At the beginning of every race the game loads stats for every vehicle into RAM and the debug menu allows you to edit those, but the game otherwise ignores them and uses the stats from ROM instead.

Debug Menu 0

These are all stats for the current vehicle.

Debug Menu 1

These are all stats for the current vehicle.

Debug Menu 2

These are all stats for the current vehicle except B, C, and D whose purposes are unknown.

Debug Menu 3

These are all stats for the current vehicle.

Debug Menu 4

These are all stats for the current vehicle except HANE, SUM, and FREQ whose purposes are unknown.

Debug Menu 5

• ROT - Determines how fast the background under the course rotates when the camera turns.
• S SP - The scale factor of the background under the course.
• CAR - The vehicle that is being played as.
• G, G DK, G BIG - These affect gravity.
• LD SH, LD P, LD R - Purpose unknown.

Debug Menu 6

These are all stats for the current vehicle that are related to its appearance.

Debug Menu 7

The number in the middle represents whether AUTO mode is enabled, wherein the player's vehicle is controlled by AI. The other two numbers represent which vehicle is being played as.

Regional Differences

Title Screen

Maximum Velocity was a subtitle change for international versions.

Japan	US/Europe	China

Vehicles

Several vehicle and location names are different in the English version, from the Japanese and Chinese versions.

Japan/China	US/Europe

Grand Prix Interface

When a competitor machine gets close enough to the player from behind, either Mark (Japan) or Check (International) displays on the bottom of the screen. Also English pluralizes Spare Machines.

Japan/China	US/Europe

Locations

Japan/China	US/Europe

Endings

After the credits, you get a portrait of the character you picked. In the Japanese version, part of the head of the character sometimes cuts off at the top of the screen. Also, there's a line of pixels that prevent the artwork from touching the bottom screen. In the western version, the portrait is a bit smaller so it fits better, and it touches the bottom of the screen correctly.

The outfits for Jane B. Christie and Kumiko were modified for the western version to be slightly less revealing:
