Cool stuff Smile going to try that right now.

Actually, I don't see a few cars here either, unless I'm missing them... So you're absolutley right, there are probably more cars we're missin' somewhere, somehow. Hook me up with the strings you're using to find these 'hidden' cars and I'll bust out some more code magic.

Search for the string: "BL10" the last entry turning up will probably be of interest. From there go down.. in this section I also found "COP_CROSS" which is Cross' Corvette.

edit: worked fine Smile though now all 90 cars are also in mycars
btw. how did you find that address and the value you need to put there?

It's code Wink Goto the address, in the disassembler, in the top/code section to see the change that takes place.

How did I find it?

- Searched for AF 2D C3 C1 AE 75 E6 28 (cop suv)
- You had said...

To make the cars appear in the stock car list just add the stockcar bit, eg. make all special cars available, replace 20 with 21.

- So I added the '20' as a byte value to my address list.
- Sat outside the dealership and right-clicked the value, then 'find out what accesses this address'
- Once I found what read it, I changed one of the jumps, to *always* jump and add the car to the list, rather then determine if it should be added or not.

It's going to be in this same code 'area' (after the return) - That we can probably change things like car price, and availability.

For anyone following this... Here's the current trainer I've got goin'.

It's not got a lot of features that I have in me ol' table yet, but it's enough for now Wink

Once again, releasing this *here* instead of under "Trainers", because it's nowhere near done.

To the folks that are contributing to this thread (cparty and... cparty). Let's combine all our talents into one big trainer. Heck, I may even gut the B&W2 trainer I created in VB and do one for NFS, depending on need.

*Edit* - Fret not Cparty. Your name doesn't exist in the trainer anywhere, because mine doesn't Wink Even in the final release of B&W2's trainer, I included my name/email addy in 0 total places =)

nice Zhoul Smile

my first attempt to disable collision comes here:

Address: 0068C7FB
Value Type: Array of Byte - 4
Description: Freeze ResetCar Timer - (Orig: d8 64 24 0c)

Notes:
After NOPing the code you need to press the reset button once to put it into non-collision mode.
As you get instant busted when your in non-collision mode, this for now only makes sense together with the "never busted" code replacemant.

*edit: it doesn't work on cars not in the save (eg. cross corvette)

Good one above... I'll see if I can refine it to work with all cars.
*Edit*
006B8813
Code: Disable Collision All (Orig: C3CCCCCCCCCCCC - New: 90B801000000C3 )

Question:
cparty wrote:
The next 2 bytes refer to the "parts-slot" and are FF if its a stock car.

Does this mean that the car(s) are modable, or not? I love the cement truck, but I can't buy upgrades for it (preformance wise), and when I add them myself in memory *crash* as soon as I 'return to free roam'.

Lastly, do you have an instant messenger? Hit me up on AIM if you have it, (LqdGroover), otherwise, I have various other messengers, so just give me a screen name.

- Z

*Edit* - If you can give me the array of bytes value for the cross, like you did with the other cop cars, I think I have a way to 'insert' cars into the buyable list.

Also,

Pointer to begining of car list:
XXXXXXXX + 414
0091BF50 + 10

Not that it ever changes on my side, but I assume that the addresses I get are not = to the addresses anyone else gets. (then again, it is a port from a console).

Every car seems modable in terms of visuals (maybe rims and a few other parts too). As you said you cannot put non-existant parts there without having the game crash though. If those bytes are FF then its a "stock" car without any mods, but as soon as you buy it (or maybe as soon as you mod something) it gets a parts-slot assigned (dummy entry):

The big mark is where the performance upgrades would be if available and the small "FF" is the parts-slot number referred to from the first section (Note: 00 - 1E are already used by the BonusCars). I don't know much about this section yet.

By adding the following entry to the first section, I added the cross corvette to the stock cars, but that didn't solve the crash error:
Code:
59 00 00 00  AF 2D C3 C1  6D 80 7C D3  01 00 01 00
FF FF CD CD

Note: you need to adjust 59 to your car in the save you are going to replace/add.

I had ICQ some years ago, but don't use IMs these days. I might install it again.

*edit*: I just tried the cement truck and the only thing you can kind of change is the color (switch to metallic/custom and back to get all colors) and you can add other gauges.. but nothing much more. Anyway those changes are stored in the parts-slot.

Yeah, Kinda tryin to figure out if there's a variable we can smack in memory that will allow preformance upgrades for these vehicles that currently crash, if mod'd in mem.

It looks good, all cars (even traffic) is blinking now, but the collision seems to be still on? Like if thats only the visual.

*edit* I think I know the reason why the game crashes when I drive the cross corvette and hit a car at high speed. I played a sprint race with the cross corvette and destroyed my car Razz like you can destroy the ai-controlled police cars. The score table showed me as "totaled" like in the drag races and I could restart. Well you can't restart in free roam, thats probably why the game crashes then.
It seems the police cars have a counter part only controlled by the ai which is not in the savegame. I always wondered why the ai can turn so fast, and you can exactly do that with the cross corvette.
Now, if we could find a way to disable damage for the usercar we might be able to play those cars (I think the normal cars dont even have damage) without crashing the game.

- While in game, press ESC
- Go to the Gameplay menu
- Car Damage - Off ?

And as for the 'code' that makes everyone blink. Heres what I've found:
If 2 entities are currently under the effects of 'no collision', they can collide with eachother Wink Now the fun part... Picking out *only* our car, from the whole lot. Smile

Well, I just lost an entire post because I chose to split it up into 2 parts Wink (the initial reply here, being what timed out, d0h!).

Since I'm tired as hell, I'm going to sum up a full page report, in 10 1-liners (not including this one and the one above it).

- Topic: Original "Infinite Nitro with the added bonus of max nitro boost" code change.

- Original Suggestion: Arrow 00693648 - Code - Nitro - New( FF ) Orig( F8 )

- The Task: Find a way, without NOP, to freeze nitro, as it was written to by an FSTP line. Arrow fstp [esi+000000F8]

- The problem: FSTP stores the stack value, then pops the registers automatically (hence the P, in FSTP). If I NOP the code, then the game will eventually crash (as will most NOPings of FSTP's).

- The solution: I found that there is a value that determines how much boost you get from nitro. It exists 4 bytes ahead, of where the value for 'how much nitro you have left' is. The theory was to let the game read my nitro value, do it's minor decrease, but modify where it writes, specifically, point it to the "Nitro Boost Strength" value, thus, giving infinite nitro and max boost strength.

- The Error in the solution: Any moron who adds 4 to F8, would not get the same result as I did the first time ( Shocked FF Shocked ?!?) . But I'm not just any moron... I'm a baked moron...

- The problem caused by the error in the solution: Writing 8 bytes ahead, instead of 4, and playing the game for several hours would result in an unexpected crash. Unexpected: until I realized what a d0rk I was. Infinite nitro is indeed an effect of the initial solution, but the latter effect sucked @$$...

- The Solution to the problem caused by the error in the solution:
Arrow 00693648 - Code - Nitro - New( FC ) Orig( F8 )


- You can find the rest of this post here: http://forum.cheatengine.org/viewtopic.php?p=28352#28352

- It was a question that turned into a few questions, then a semi-tutorial, so I posted it under the tutorials section. Before you ask, yes I had a lot of transformers in my younger years.

- Z (this line also exempt from total line count).

The game option settings get stored near the player money, though turning damage off had no effect on the police cars (cross still crashing).

As for the nitro code, I found that there are 2 or 3 fstp operations.
One is after fadd (refill nitro) and one after fsub (when using nitro).
So I just replace the fsub and all seems fine:

Is it just me, or is this 'damage' feature a bit misleading? When I left it enabled, I was expecting at least 1/2 the damage that you'd get in any of the Nascar series. I was (oddly) a bit disappointed to see that, after 1 hour cop chases (on purpose of course), the car only appeared minorly scratched/scuffed, yet I had bust through more then a dozen road blocks, and took out at least 50 cop cars...

Aye sir. I left the + writes alone, and expanded on the FSTP topic, more-so for tutorial purposes, but also because it just-so-happened that the "Nitro Boost Strength" (hence forth known as NBS, because it sounds so ghey when typed many times in the same reply) value was staring me in the face, just asking to be written to.

You've just inspired another thought however. I'm going to change the fsub into an fmul, and write *that* to the NBS value Cool If I'm alive after testing and it's worth a shat, I'll post this in teh trainer.

So where's teh save game? Cool

Seriously though(which isn't often): I'd like to include some kind of wicked save game with the releases of the trainer im casually working on, so if you've got one with all those cars, added in career mode, I'd love to get-a-hold of it.

Once more, this request surely isn't for falsified fame, as I don't include even my own name in nearly all releases.

*edit* - I'm usually pretty picky with releases, and like to only affect a game, via a trainer, more specifically, live mem hacks. Tiz an honor, that I ask for a save-game... or at least a rarity Cool

You already have it Wink it's even in a blank savegame. Its the stock car list (00005E31 - 00006218). I already have a 100% savegame and the clone savegame I posted earlier containing the police cars. I will probably build a new one once we know a bit more... I wonder what makes more sense, adding the new cars to the stock cars so the user can buy/add himself or just add them to career/my cars?
