You certainly are the brains when it comes to hacking Xenn.👍

We should, but that might take a while. I'm still messing with the body codes of that other car code I've shown a while back where I found a solid red viper and a silver daytona cobra.
Im wanting to find every possible car on there. That code i posted on the Searching for evidence of hidden things covers alot of them i believe but you cannot change the color. Im wanting to find them and find out what color options they have as well as any hidden cars.;)

Funny that you say that SonyGamer, because I already tried a code for the Dodge Viper GTS and it fricken works!

Like in GT1, it only comes in 2 Colors; Blue w/ White Stripes & Viper Red

EDIT: did the same thing to see if the Dodge Neon R/T is in the Demo and it is, but the game crashes when I try to race it.

It's possible the Neon R/T might work through different methods. I could post an entire list of codes here, but there'd be so much to scroll through.

True, I mean; I've seen a couple of codes used on other cheat code forms to prevent the game from crashing. I tried the same thing for the Viper RT/10 & 1998 Mustang SVT Cobra and they both crashed. The body for the '98 Mustang Cobra isn't rendered yet BTW; it's just using an Altezza body for a placeholder.

EDIT: Anyway, I have a whole bunch of time since the blizzard had an effect on the state I live in; so I guess I can try to go through some more cars. I'll take screenshots if I find anything interesting and they'll show up on the 'hidden things' thread for GT2.

It seems trying to load some cars from the arcade menu makes the game crash. So to get them to work outside the menu, you'll need a body loader.

801D194E 0E35

Best to turn this code on in the arcade menu, then when the race loads you'll have the Neon R/T body.
 
^Awesome, thanks. I can also drive that Ford GT90 possibly.

If you use the body code next to the car code on the website, make sure the last 4 digits come first, then the first 4. Like this:

0E34B3D8 | Dodge Avenger

Red first, Blue last.

Oh yeah, that's probably why the code didn't work when I loaded it with the Ford. oops. alright, the 3rd time is the charm I guess.
 
Pretty sure I already made a code like that.

Your car sounds like the CPU (NTSC 1.2)

I think these codes should be added. They're codes for Euro Demo 53 given to me by Mattj55 from youtube:

Gran Turismo 2 3rd Demo Codes:


Track Modifier

80098650 00??

Access Home Garage

D0029840 0081
80029840 0001

I would also like to know how to make my own codes so I can create some codes for the 3rd demo myself. I'm having a hard time with google though.

Oh yes, I did those codes a while ago but forgot to post them here. Thanks for that, i'll add them to the first post.
 
Hey folks, still no news on how to change position on the starting grid ? I know it's an old one but i'd love to try it out, if it's possible :)

^Just tried it XD

It was fun to try, dirt trial apparently causes the game to crash.

Let me know when you find a way to use a mustang GT replacement code like in the 2nd demo. I want to see how many more cars were finished and are driveable this time.

Do you know how to set up other positions ? I tried to play with the value but it doesn't seem to work right...

Starting Position Modifier (PAL)
301D5975 000X <-Player 1 Starting Position
301D5A45 000X <-Player 2 Starting Position
301D5B15 000X <-Player 3 Starting Position
301D5BE5 000X <-Player 4 Starting Position
301D5CB5 000X <-Player 5 Starting Position
301D5D85 000X <-Player 6 Starting Position

You can use 0 to 5. 0 is first, 5 is last and so on. Make sure to change the positions accordingly. For example...

If you choose to start in 3rd, you must make Player 4 start in 6th.

Thanks so much, works perfectly :) The only thing is that if I want to switch positions a second time, I have to restart the game, otherwise I'll still be on the first setting no matter what value I put. But that's no big deal ;)

What version is this - PAL? :indiff: If possible, can you convert it to NTSC 1.0?

Try this one. I don't have 1.0, but I might've guessed the conversion correctly.
 
This code was given to me by a guy on youtube named Hacczilla. It's for the Gran Turismo 1 Demo, it can be used I think on Playstation CD Interactive Sampler discs Vol 8 & 9. It basically gives you access to every car in the demo.

Hey, I have been having some problems with these hidden car codes. I had put in the code correctly, and it saved successfully, but when I go to turn on the code before I put the game in, it won't select it. The codes were for the GT3, Chrysler Viper race car, and the Diablo (the Diablo I didn't actually put in, but I assume something similar will happen). I'm not sure what's going on, and I had posted a thread, but I haven't had any responses.

When you say it won't select, you mean the cheat won't be active? Or the car can't be selected?

I could make up a code similar to that and see if it helps any.
