Widescreen Gaming Forum

I decided to reinstall MW2 last night and the fixer did not work for me in SP. I've used it for Black Ops and it was fine, but MW2 is just not working even though it's recognizing the running game and it toggle on and off in the fixer window.

I got the same problem as _CH_Skyline_, the Widescreen fix wasn't working, detects the game but didn't change anything on the actual game.
Debugging the process I saw it does write into the process memory, but the offsets for the version I've are not valid. (who knows what was overwriting 8)

static Call_of_Duty_6_SP_168()
{
_gameName = "Call of Duty: Modern Warfare 2 SP";
_offsetAspectRatio = 0x75e018;
_offsetLeftHud = 0x936558;
_offsetRightHud= 0x936560;
_offsetXRes = 0x936520;
_offsetYRes = 0x936524;
_offsetScaleH1 = 0x936514;
_offsetScaleH2 = 0x936504;
_offsetScaleV1 = 0x936510;
_offsetScaleV2 = 0x936500;
}


Doing some more digging, I found the values for my version are 0x4000 bytes off from the values in Call_of_Duty_6_SP_168.
e.g: 0x75f018 for "Aspect-Ratio" is 0x762018 in the version of my exe.

So, hexedit the "Game.Call of Duty 6 SP.dll" search for the values above,
and replace then for the same value plus 0x4000.
0x75e018 -> 0x762018
0x936558 -> 0x93A558

and so on...

After that, I can get 5280x1200 (SoftTh) working fine, correct ratio and fov.

The offsets you see there are not the actual offsets that get used. :)

Anyway, there must have been a patch some time to MW2 that went unnoticed.

Steam also uses dynamic binary generation so that may have some role in it, too.

I'll redownload MW2 and try it out.

Much appreciated as always!

Umm.. not sure what you mean with that.
Those variables contains the offset in memory where the game stored the values, and those are the ones used by your app

public void Enable()
{
int processID = WSFFunctions.GetProcessID(_exeName);
if (processID > 0)
{
this.Enabled = true;
WSFFunctions.AspectRatioSelection = this.AspectRatioSelection;
byte[] aspectRatioByteArray = WSFFunctions.GetAspectRatioByteArray();
float aspectRatio = WSFFunctions.GetAspectRatio();
IntPtr handle = WSFFunctions.OpenProcess(0x38, false, processID);
IntPtr zero = IntPtr.Zero;
WSFFunctions.WriteMemory(handle, (IntPtr) _offsetAspectRatio, aspectRatioByteArray, 4, ref zero);
byte[] buffer2 = WSFFunctions.ReadMemory(handle, (IntPtr) _offsetXRes, 4, ref zero);
byte[] buffer3 = WSFFunctions.ReadMemory(handle, (IntPtr) _offsetYRes, 4, ref zero);
...
...

For my exe those were invalid, running Winhex opening the whole memory for the iw4sp.exe process shows the memory at those addresses been overwrite with the new calculated values.

The only place in the whole code where those variables are assigned is in the constructor:

static Call_of_Duty_6_SP_168() (after the hexedit +0x4000)
{
_gameName = "Call of Duty: Modern Warfare 2 SP";
_gameDescription = "This plugins corrects the aspect-ratio for surround users. It does not modify the field-of-view.";
_gameVersion = "v1.0.168";
_defaultVersion = false;
_timerNeeded = false;
_exeName = "iw4sp";
_valueTitle = "Aspect-Ratio";
_mainHudV = 480f;
_steamPath = @"steamappscommoncall of duty modern warfare 2";
_offsetAspectRatio = 0x762018;
_offsetLeftHud = 0x93a558;
_offsetRightHud = 0x93a560;
_offsetXRes = 0x93a520;
_offsetYRes = 0x93a524;
_offsetScaleH1 = 0x93a514;
_offsetScaleH2 = 0x93a504;
_offsetScaleV1 = 0x93a510;
_offsetScaleV2 = 0x93a500;
}

and different offsets for the 1.75 version:

static Call_of_Duty_6_SP_175()
{
_gameName = "Call of Duty: Modern Warfare 2 SP";
_gameDescription = "This plugins corrects the aspect-ratio for surround users. It does not modify the field-of-view.";
_gameVersion = "v1.0.175";
_defaultVersion = true;
_timerNeeded = false;
_exeName = "iw4sp";
_valueTitle = "Aspect-Ratio";
_mainHudV = 480f;
_steamPath = @"steamappscommoncall of duty modern warfare 2";
_offsetAspectRatio = 0x75f018;
_offsetLeftHud = 0x937558;
_offsetRightHud = 0x937560;
_offsetXRes = 0x937520;
_offsetYRes = 0x937524;
_offsetScaleH1 = 0x937514;
_offsetScaleH2 = 0x937504;
_offsetScaleV1 = 0x937510;
_offsetScaleV2 = 0x937500;
}

Anyway, it does work for me, I just wanted to help others who may be running a different version, or at least try to explain them why it may not work for them.

I'm sad to say that, after having just re-installed CoD4 (retail), it is not working either. It shows as working, but is not.

I had that issue to, the steam and retail or mixed up, run the fixer for steam version instead

I'll try that tonight, thanks.

EDIT: Steam .dll works with the retail version of CoD4 as suggested.

Black Ops just updated today. :cheers

EDIT:
And 2 hours after I post this the fixer is updated.. Dopefish for president!

Black Ops just updated today. :cheers

Ive just put a ticket in today

that will explain why the fixer isnt working
