PS2 Widescreen Hack (Hex ISO Codes Only)

[nemesis2000]

Did you notice frame drop on final fantasy XII with 640 x 448 mode?

i didn't notice any frame drop, but i noticed that some graphical effects, static images has own resolution values which i can't find and that causes some graphical glithes

and how could you find the addresses in the first place? I want to try other 512 x 448 games too.

Mortal Kombat Armageddon has unusual resolution 832x448, that helped me to find right hex code

and i noticed that hex code always looks like

yyyyxx24

where yyyy resolution

c002 - 832
8002 - 640
4002 - 576
0002 - 512
e001 - 480
c001 - 448
a001 - 416

and x can vary between 01-10

so for ffxii hex code
00020224

for mka
c0020324

Does anyone know a way to apply the widescreeen cheats to game elfs , and tell the exact process.

i tried for RE CV, but there is 1505 possible values for 0000804f, and its hard to find right one

maybe that can help, but I do not know how

@nemeesis2000:

thanks for the detailed info.

But how did you apply these changes? Did you get the game elf out of iso, applied the hex change via a hex editor and put it back to iso?

Sorry if i am bothering you. I just want to learn the exact process(best program to take the game elf out of iso, and rebuild the iso back, and the hex editor you use)

i applied the hex change to elf file via a hex editor

then i put dvd in ps2, and launched modified elf from usb flash

for pcsx2 i mount iso, and launched modified elf file

Of course you can extract the ELF, modify it, and then rebuild the iso. But the rebuilding is a bit complicated since the exact file order is (at least for some games) important. And it's not necessary for these resolution hacks either. Just use a hex-editor that allows you to modify a user-defined range of the ISO image. I use 'Tiny Hexer' for these purposes, I don't think it's something super special but it gets the job done and is easy to use.

thanks to nemesis2000 and No. 47. I will see what i can do.

To the contrary, I'd really like to see how much the framerate can be improved by decreasing the internal resolution. Maybe games like Killzone that are nearly unplayable due to sluggish framerates can get a nice performance boost by sacrificing some image quality? Although somehow I doubt it, these games probably are simply unpolished as a whole...

One of the other ideas I had.
BTW, I tried the force480p trick on the ELF of KH2FM and it did work differently indeed than doing it with GSM.
Now I need to decide what's better, 480p with this trick or 480i with a good de-interlace that my TV has?

and some information about games that uses renderware

RwCamera* RwCameraSetViewWindow ( RwCamera * camera,
const RwV2d * viewWindow
)

RwCameraSetViewWindow is used to set the size of the specified camera's view-window (in world units). The specified 2D vector represents the half-width and half-height of the view-window. The default view-window has dimensions (1.0, 1.0) giving a window 2.0 units on each side.

This function can be used to control the angular field-of-view of the camera. Larger values give a wider field-of-view while smaller values give a narrower view. Hence changing the size of the view-window gives the effect of a zoom-lens. Note that changing the size of the view-window does not alter the size of the camera's image raster, so unless the aspect ratios match, the resulting image will be distorted to conform to the image raster's aspect ratio.


Note:
This function should not be called between RwCameraBeginUpdate and RwCameraEndUpdate.

Parameters:
camera Pointer to the camera.
viewWindow An RwV2d describing the view-window dimensions.

Returns:
Returns pointer to the specified camera.

Wow, that's awesome!! I tried to patch that game via memory hack some time ago and failed... do you know if that should work as well or is it necessary to hex-edit the ELF? I really have to look into this tomorrow.

it works well only for gameplay

but i've made some corrections for no prerenderd cutscenes
