GTA Vice City, how do I enter cheats?

[ShawnD1]

I've found a lot of cheats on the internet but how do I enter them? Hittin the ~ key doesn't bring down a console and simply typing the code in does not work. Do I need to make some special shortcut to the game or something?

a) Open up Vice City and load the last saved game
b) Type in the cheat... Just type it.

During game play just type the cheat. If you didn't fat finger it typing it, you will see a window pop up that says, "cheat activated".
