Alright cool!

I just tried it again and it seems a bit more complicated.

I swapped between those two cars, tried to do as many actions as possible (crashing/doing damage, leaving area, using nitrous etc.) so get rid of as many values/addresses as possible.

I don't know what I had done earlier to only get those two values, but now I'm stuck with around a thousand values. They all seem to be linked to the vehicle: I swapped the vehicle and instead of searching for a changed value, I searched for an unchanged value. The result: 0 found.

Bad sign right?

Leaving area? Bad move, very often when you change maps or get a loading screen your values in memory get shuffled around.

If I were you I'd do my scans without leaving the garage.

[Ozzy25]

Wow I never thought of that, I loaded the car every time and then drove around and did all kinds of stuff. Perhaps I should do it again while staying in the garage.

But why by the way? I mean the value for the car should stay the same.

I didn't really change map, I just went far away from the starting point. (Ok, not really. Like 1 minute haha)

No I swapped once, to another vehicle, and did this search on purpose to find out if these values were actually linked to the vehicle or not!

I've now decided to select some other cars and every 2nd car I return to the car I started with / the first car basically, with which I made my first scan. I don't manage to loose any values unless I change car, so far only 108 values left.

After that I'll try doing this in the garage!

Thanks for the tip.

So I tried doing it in the garage but it's almost even more difficult as there's exactly as many values to start with (at least a hundred millions) but it's much harder to get rid of them. All I can do is select a car, or select another. And in cheat engine all I can do is search for a changed or an unchanged value.

Earlier I took a car from the beginning of the list, and another more at the end of the list. So I tried searching for increased and decreased value but obviously it wasn't this, probably they're in a complete different order than they're presented to us.

Ah, if your garage come with a 3d representation of the car, try lowering all graphic options to their minimums. Small resolution texture means less data loaded in memory, and the less data is loaded the faster the scan and the less false suspects there are.

But ultimately it boils down to a fight between the game and your patience. Don't forget trial and error when filtering becomes ineffective and you have, say, less than 5k remaining suspects (iirc 10k->cheat engine will hang).

[Ozzy25]

Nope not a 3D garage just I think the map outside is already loaded (actually I'm pretty sure it's the case).

I tried setting it to minimum but no changes!

Also in the game files I found some files with a list of vehicles, with numbers. They're not in the same order as in the game.

I tried:

- Finding a car with a number in that file.

- Selecting the car in the garage

- Searching the number (exact value) that I found in the file

- Chose a second car from the list in that file

- Selected it in the garage

- Searched for changed value

- Searched for exact value (number from the second car)


The result was that I always found 2 values that changed accordingly for both vehicles with the correct numbers, but as soon as I tried a third vehicle, the number stayed the same so it was all wrong I wish I had found it haha!


But I'm ok with patience. I like doing that also, it's kinda fun.

BTW — could it not be something else than a 4 bytes value?


Also, is it possible that it is impossible to do that? Or is there a 100% chance that this works, even if it's really hard?

Hmm interesting. Thanks for sharing!

By the way, as for the value type: I noticed in the game files that some vehicles share the same vehicle files, yet they can have physical differences.

Obviously they can also have different colours.

Does that matter? I thought this information could be saved in there. Because I thought this would make the values even more "variable" perhaps.

Edit //

I believe I found something

Did the same process again, with filtering etc. and narrowed it down to 25 values. All 4 bytes.

Two of them I know it's not them, I've already found them earlier when filtering so I can exclude these.

But then I have around 20 addresses or so, of which 10 use the exact same value, and it changes every time I change the car.

Then 5 addresses use the same value too, and another 5 addresses also use the same value.

Could this be something?


Edit 2 //

Restarted the game, and sadly, all values had changed.

But I have searched for the values again (4 byte > exact value) and found them, so they changed addresses (Now we come to that part with changing addresses, where I'm still so confused…).

The addresses were the same as before for each car that I had selected. So those are definitely the addresses to the cars

Earlier I said some cars can have physical changes although they share the same vehicle files. I noticed that too: I tested such a car, which has the exact same performance, handling etc. as the standard version, but it comes with a spoiler for example. I compared it to the "normal" car and one value was changing. Probably the one for the spoiler. I tried selecting the normal version and changing the code to the code for the spoiler and freezing it, but it did not really work (one reason I restarted the game, I wanted it to be "fresh" as maybe it can't do everything in real-time sometimes).

Funny thing was in the garage the car logo disappeared sometimes depending on what I changed, and usually also I have a "Are you sure you want to select this car?" window, but it skips it extremely quickly and it doesn't show any selected car. However if I start driving, then this car is selected.

I think this sounds good so far?

[Ozzy25]

Gniarf, any ideas?

(Sorry for the double post…)

Thanks for replying!

Sadly, it seems like I've lost track of all values. I had written them down, some of them I find them, some not, some of them don't change anymore. But I was 100% sure they were linked to the cars, they only changed when I changed the cars, I tried doing pretty much everything you can do and they never changed, except if I changed the cars.

Some of them I still have them, the "main" ones which define a car. But the ones that define a special version, for example a spoiler… no chance (Or at least those that I thought they may be for a spoiler for example).

As far as the steps you listed go — I did what you said with two normal cars, since I don't find the values for the "special versions" of cars anymore.

Every car has ~ 14 values or so, and these change when I change the car. So I did all the steps you said until #5 and to my luck there was only one line I clicked Replace and a very weird screen appeared and after a few seconds the game crashed!

And what did you mean with "push"? Do you mean that the word "push" is in there? If so then it isn't (there was only one line like I said so I can't have missed it ).

I'll test some more stuff now and we'll see if I'm lucky!

Thanks by the way for all the help through the topic, without you I wouldn't have come so far

Alright wait a second — I had to figure out the values of the cars again. I can't figure out the values that I thought determined the small differences (like a spoiler) anymore, so instead I concentrated on just finding values of the normal cars that I can drive.

So now I have the addresses + their values (well, their temporary addresses, but the values are always the same).

When I said there's 14 values and they all change when I change the car, I forgot to say that those 14 values are all the same, and when I change my car they all change to another same value. So I have 14 times the same value.

There was one however that was a bit different: the value changed to zero when I was in the garage, without any car selected. The others stayed this way. I think this is because it somehow saves the car you were using so when you start a race for example and you didn't select any car, it would use that last car you had.

So I did step 1-5 again like you said, and I came to the "following opcodes…" window. This time however I had two lines. Both counts for both lines are getting higher and higher and don't stop, not sure what these mean.

Those are the two lines:
