cheat entry for cars ds

Hi

Where the heck is the cheat code entry spot for all these cool codes

The codes I wrote down from this site and from cheatplanet.com For infinite nitro, all minigames and cars etc... They all start out saying enter vroooom or something else for example in the cheat entry screen. But I don't know how to get to the code entry screen. The vroooom code is for the infinite nitro. I hope you can collaborate with me and help. THANX!

I think someone either made a mistke or is messing with you guys because I've had this for a year and there is no cheat entry screen.Sorry;(

With the word codes that people have been given, well, they are all fake! there is no code menu so they are just playing you! but there are two codes that do actually work and so if you want to know them then just go to cheats on neoseeker. The cheats say at the start menu. If you don't know where that is then just follow these steps:

1. Turn your DS on
2. Select Cars
3. There should be a car with all the credit type stuff on
4. when you see that then quickly type in what it says to
5. repeat step 4 a few times and then when you get onto your game it will have all the things that it said the code will do

if you do these five steps then you will have all the things that you wanted.
Hope i helped
Cars Dude!
but before i go does anyone know how to get all the cars/games without the help of the cheats/codes? I had been playing for ages but i didn't get anything extra so i turned to the cheats. Now i have sort of finished the game in a way but i don't feel like i've achieved anything because i cheated. So has anyone out there finished the game with out the help of cheats?
