I've uploaded the

patched EXE for TR3 and The Lost Artifact. It includes my (exclusive) FOV patch. It was was not published anywhere until now.

That's how it works. There is the original code (let it be C pseudocode):

Code:

#define SCREEN_WIDTH dword_5A6AF4
#define SCREEN_HEIGHT dword_4D790C
#define ASPECT_RATIO flt_4C3244 // *1.3333334*
**void** sub_402030(__int16 a1) {
**int** v1, v2, v3;
v1 = SCREEN_WIDTH / *2* * sub_4B4C58(a1 / *2*);
v2 = sub_4B4C5E(a1 / *2*);
dword_4F6D50 = v1 / v2;
v3 = sub_4B5E10(v2, v1 % v2, flt_4C5084);
dword_5A6A28 = v3 / dword_4F6D50;
flt_5A6AB8 = (**double**)dword_4F6D50; // heigth ratio
flt_4F6D48 = flt_4C5084 / flt_5A6AB8; // depth ratio
flt_53170C = flt_5A6AB8 / flt_56C0A0;
flt_4D38D8 = ASPECT_RATIO / ((**double**)SCREEN_WIDTH / (**double**)SCREEN_HEIGHT);
sub_48D6A0(v3 % dword_4F6D50);
}

And I've changed it to this code:

Code:

#define SCREEN_WIDTH dword_5A6AF4
#define SCREEN_HEIGHT dword_4D790C
#define ASPECT_RATIO flt_4C3244 // *1.3333334*
**const float** flt_4D38D8 = *1.0*; // it is always *1.0* now
**int** sub_4020B8() {
return (**int**)((**float**)SCREEN_HEIGHT * ASPECT_RATIO)
}
**void** sub_402030(__int16 a1) {
**int** v1, v2, v3;
// SCREEN_WIDTH value replaced by new function sub_4020B8
v1 = sub_4020B8 / 2 * sub_4B4C58(a1 / 2);
v2 = sub_4B4C5E(a1 / 2);
dword_4F6D50 = v1 / v2;
v3 = sub_4B5E10(v2, v1 % v2, flt_4C5084);
dword_5A6A28 = v3 / dword_4F6D50;
flt_5A6AB8 = (**double**)dword_4F6D50; // heigth ratio
flt_4F6D48 = flt_4C5084 / flt_5A6AB8; // depth ratio
flt_53170C = flt_5A6AB8 / flt_56C0A0;
sub_48D6A0(v3 % dword_4F6D50);
}

There are v1, v2, v3 variables to calculate FOV. I changed the formula so that they depended on the original aspect ratio (4/3) and the current screen height, but NOT screen width, because this is not correct for wide screens.

The flt_4D38D8 variable is pixel aspect ratio. It must always be 1.0 if we want correct aspect ratio.

P.S. Do not combine this patch with other Widescreen patches and Peixoto's patch. They will break the formula.

**UPD. I've updated the patch. Old links deleted.**
