Crazy Taxi is the first and most popular game of the Crazy Taxi series. It was first released for Arcade, and then ported to several other platforms, including Windows.

Unused sounds

There are some unused sounds in the sounds file Voice01.afs.

7 minutes mode

There's a sound for starting a 7 minutes mode cut from final game.

Arcade sentence

There's a sound for the arcade machines that is still present in this file for the PC version, and probably present for all platforms. However, it's never heard in either of the Windows versions.

Crazy box

When starting a crazy box challenge, we can hear "Ready" and then "Go". The sound file containing "Ready" also has the words "get set", which is never heard.

There are also unused sounds for remaining customers. The max number of customers for any Crazy box challenge is 8 from Crazy Pole. There are sounds for 10, 9, and 8 remaining customers that are never used.

Original Gus voice

To do: There seem to be some Arcade revisions that have Gus's original voice.

It seems that Gus' voice was rerecorded or altered at some point. Gus's original voice is included in the sounds file for all his sentences. It was used in the original Dreamcast version and was changed in later iterations. Here is an example:

Sound debug log

If you run the game executable in a debugger, it will print audio related debug messages in the debugging console. Some of these messages are:

Failed to start MP3

Playing music %i, %i

Setting music stream volume to %i

Unused Text

These texts are found in the Windows executable.

Gena's weight

In Crazy Box mode, when selecting a driver we see a list of details of the drivers, including age, sex, height, weight, and blood type.
Gena's weight is the only weight not shown, being overwritten with "??". If we look at the driver details in the Windows executable, we can see Gena's weight is 114.4lbs for the English version and 52 kg for the International version. It's unknown why this was changed.

Unused Crazy Combo

Crazy Finish!

Early development Crazy Box challenge names

Early Crazy Box challenge names are present in the Windows executable.

There's a text zone in the executable with strings that seems to be related to a debug HUD for a gameplay recording mode (Like the one from the Press Start screen). They are grouped in different blocks.

Japanese Copyright screen

There's a message supposed to be from some kind of Japanese version of the game. It's present in the International version (and obviously unused).
