(adsbygoogle = window.adsbygoogle || []).push({}); Hi everyone,

Welcome to Vextriixx's first tutorial and the first tutorial of modding GT5! I think it is about time that this method should finally come out (sorry for those who are going to hate me for releasing this but its bound to come out sooner or later and the quicker its released the quicker it will get patched etc) - here I will give you a step by step guide on modding the GT5.0 file within the GT5 save. It is very simple and very little things are required.

Things you will learn about modding ( will update when I find and decide to release new things or someone else has found something) :

  • Money
  • A Spec Level
  • B Spec Level
  • Horsepower
  • Ride Height


MORE TO COME SOON (LIST UPDATED 2ND MARCH 2013)


Required Items/Applications:

  • FAT32 USB Stick
  • PS3 (Obviously - can be any FW)
  • Aldotools BruteForce
  • A Hex Editor (preferably HxD)
  • Big Endian Tool (not essentially needed but can be helpful to find it just search the forums)


So lets begin. All editing will be done in hex as I believe there is currently no easier way of doing so - well untill some tools are released that is.

[multipage=Decrypting the Save]

This part really doesn't need a page but there are still some people out there who may not be able capable of using a bit of common sense. To do this you are going to need Aldotools BruteForce application (there are other tools you can use to decrypt the save but this is my recommendation). It is simple to use.

You must login or register to view this content.

Here is the basic screen you will get with Aldotools. Just navigate to your selected save you got off the PS3.
Right click on the GT5.0 and press 'Awesome faceecrypt PFD'

Once that is done you should end up with a screen like this:

Now double click the GT5.0 file and it should open up HxD.

[multipage=Changing The Horsepower Multiplier]

Right, I'll jump straight to the part everyone wants to do which is multiplying the base horsepower of the car. It is quite simple, easy and quick to do (you can have your modded car in just a few seconds). The first thing you want to do when HxD opens up is press Ctrl + G this will bring up a goto pop-up box. In the offset box you want to type in 0000E960. Like below.

You must login or register to view this content.

Now this should take you to a part of the save that looks roughly like this:

You must login or register to view this content.

From what I know about the save - Polophony Digital (PD) have scrambled the car data across the save. Around this offset is the majority of the car data for the car which is currently being driven. But we are interested in the multiplier - nothing else at the moment. You want to browse around the offsets surrounding this area until you find this (in case the image has gone it is the hex values of 28 00 00 00 64) :

You must login or register to view this content.

After the 28 is the hex value of the multiplier. This is the only byte that needs changing. Before you start editing I will briefly tell you what this does. As far as I believe this value will multiply the original horsepower of the car before any upgrades etc. were added to it. So for example if you had a car which was originally 100 bhp and changed the hex value to 0A (10 in decimal) this would make the horsepower of the car become 1000. In order to make realistic cars I recommend using the values between 05 - 09. However if you wanted to make a ridiculous car you could change the value after the 28 to FF (255 in decimal) this would now make and 100 bhp car have 25500 bhp. So its just simple maths.

Unmodified car:

Modified car:

And that is simply how to change the horsepower of the car.
NOTE: TO ACHIEVE THE STUPID SPEEDS YOU MUST CHANGE YOUR GEAR RATIOS OTHERWISE YOU WILL PROBABLY STOP ACCELERATING AT A CERTAIN POINT. ALSO SOMETIMES GT5 WILL NOT NOTICE THE CHANGE SO THE GAME MAY NEED TO BE BOOTED TWICE (NOT SURE IF THIS IS FOR EVERYONE OR JUST MY GAME PLAYING UP) AND TO MAKE SURE IT WORKS BEFORE DOING ANYTHING GO INTO THE TUNING SHOP AND JUST PRESS THE X BUTTON AN UPGRADE LIKE 'ENGINE 1' - YOU DON'T HAVE TO BUY IT BUT YOU MAY AS WELL ANYWAY.

[multipage=Editing the ride height of your car]

As you may be aware the value we just edited with the multiplier is the key area for where the majority of car data is stored. So it would be no surprise that to find near here that the ride height/suspension of the car is found. Simply just a few bytes away from the multiplier. The ride height consists of two bytes. The first byte controls the front end of the car and the last byte controls the back end of the car so simply mess around with these values you will end up with something looking very interesting. Right so lets get to it.

First of all you just want to do a quick scan around of this offset I told you to look at for horsepower (0000E960) and look for a block of FF (these are the tuned parts fitted to the car) As you can my block of FFs last for 3 whole offsets.

You must login or register to view this content.

Approximately 3 lines under those FFs you will find to values which are roughly the same (providing you haven't changed the ride height) in my case I have '46 00 46' if you haven't touched the ride height the values should roughly be around this.

You must login or register to view this content.

As you can see I highlighted the values you are interested in looking at. Simply to make the ride hight smaller you reduce the numbers. I recommend using the calculator on your computer in programmer view to quickly swap between decimal values and hex values.

You must login or register to view this content.

I want to make a 'slammed car so lets make the ride height very low. Lets change both the 46's (46 is 70 in decimal values) to 06 (06 is 6 in decimal).

You must login or register to view this content.

Now you have successfully altered the ride height.

[multipage=A and B Spec Level]

Right I have finally got around to updating this thread so here it is A Spec and Spec level. This is a tad different to some of the others as we are going to be searching the save for Big Endian values. In order to do this you must know what your current levels.

First of all on your decrypted save you are going to need to press CRTL + F to bring up the search window. After this has been done - choose the options so it looks like it does below.

You must login or register to view this content.

Now you are going to put your A or B spec level into the 'search for' (I am currently A Spec Level 20 and B spec 0 in this save), so I will search for that)

You must login or register to view this content.

Here I searched for a big endian of 20 which is 00 00 00 14 in hex (you can tell when you are at the level bit because both levels will be near each other) no I will search for a big endian of 0 because lots of 0's are in the save I will simply just search for 00 00 00 00 in the hex number.

[img]https://puu.sh/2blqx[IMG]

As you can see in that screenshot the 00 00 00 14 is slightly above the 00 00 00 00. Now we will change them. As you should know the top level in GT5 is level 40 and the big endian value for 40 is 00 00 00 28. You will also notice that the endians are surrounded by 03 - this is a big give away that you're in the correct area. Simply replace those values with 00 00 00 28. As shown in red below.

[IMG]https://puu.sh/2bltJ[/img]

And well now you are level 40 on both A Spec and B Spec - it would interesting to see if anyone wants to experiment and try going above the level 40 and see what happens.

[multipage=Adding Money]

Right now its time for adding money - however there is one downfall for this you can still only go to 20 million; if you go higher I find that it either won't stick and it just resets or you can't buy anything (I have heard people have been successful with this but I'm not sure). Again we are going to be searching for big endian values. So it is important you know the amount of credits you have.
Like what we did with changing the levels bring up the following box using CTRL+F and make it look exactly like my box. In the 'search for' type how many credits you have.

You must login or register to view this content.

I have exactly 16,560,200 so I'll search for that; the easy thing about credits is you will probably only need to do one search as the endian will only appear once. (Unless your on 0 credits in which case you'll just have to remember the offset at which the credits are stored which is roughly 0000F280 or around that area). Here is where my credits were:

You must login or register to view this content.

Now the big endian value for 20 million is 01 31 2D 00. So simply just replace your current hex values with that. It should look like so:

You must login or register to view this content.

And now that is done you have successfully altered the amount of credits you have - again feel free to experiment as experiments are were you make great discoveries!

You mean you are trying to mod your GT-R SpecV Black Edition?, are you sure you have the car currently in use or are you trying to hex the car when you have another car selected as in use?

Which part are you hexing? according to the guide or just some other random part where you have found the exact same hex numbers. An idea would be to post a screenshot with ideally the surrounding offset areas.

No you don't need a jb ps3 to do this otherwise people would have mentioned so.

Figures out how to decrease gears and change gear ratios via HxD but don't know how to increase how many gears I have :(
For example : I made a skyline specV R35 have 5 gears but couldn't make a mustang mach have 8 gears :( Been studying the 5,6, and 8 gear cars like mustang gt, skyline, honda civic, and ISF. Still no luck

^ it would be cool to figure out if there are any "unknown" transmissions. If you take a look in the eboot the order of the gears is laid out just like in the gamesave, and there are 11 (!) gears.

each uses two bytes in the save:
Reverse Gear, 1st Gear, 2nd Gear, 3rd Gear, 4th Gear, 5th Gear, 6th Gear, 7th Gear, 8th Gear, 9th Gear, 10th Gear, 11th Gear, Final Gear

Theres definitely space in the save to do 11 gears I think Winky Winky

Nice Mint Sauce, do you have the offsets for the gear ratios? I want to try get 11 gears on my lotus Smile
