Be warned that using cheats may cause unintended side effects, disable achievements, and/or hinder game progress.
Use cheats at your own risk.
This page shows all the available cheats in Grand Theft Auto: Vice City. They are activated by a button/key combination. Cheats can be inputted into the game at anytime during gameplay, including in the pause menu. For the Xbox 360 version, all black and white buttons are equivalent to the right and left bumpers. A successful input of a cheat, either activated or deactivated, will display a "Cheat activated" message. The usage of most cheats will decrease the criminal rankings by 1,000 points. Cars will only spawn on the closest car path node, not in front of the player. Attempting to save the game after inputting certain cheats will pop up a screen warning the player not to save the game after inputting cheats. Some cheats can be disabled by reinputting the cheat code, some can be disabled by reloading the game, but only the pedestrian hate and riot cheats are permanent and cannot be reversed if the game is saved while the cheat is active. These pedestrian-related cheats can hinder progress during missions.

The effects of the Peds Riot cheat extend to gang members, including people from the Vercetti Gang and the army troops stationed at Fort Baxter Air Base. However, they cause little damage to each other, while Tommy himself suffers no damage from Vercetti-affiliated people.
The pedestrian riot also behaves in some sort of food chain; where some NPCs only attack other NPCs, some attack Tommy only, and those who attack both Tommy and NPCs.
The cheat for black traffic in the PC version is "iwantitpaintedblack". It's a reference to the 1966 song "Paint It Black" by The Rolling Stones. Furthermore, a line in the song is "I see a line of cars and they're all painted black".
If the player starts a mission with a "Play as" cheat activated (except "Play as a pedestrian" cheat), Tommy will assume the appearance of that character during cutscenes.
Although some cheats cannot be reversed during gameplay, the cheat that speeds up gameplay can be completely deactivated by entering a mission, even something as simple as a Vigilante mission.
