Hey all,

a friend noted on gtareactor that Vice City has problems with 16:10 resolutions (like widescreen monitors have). This showed in a difference between the crosshair and the actual hit point. See the screenshots below if you don't know what I'm talking about.
From that on I worked on improving the display and fixed some minor stuff.

Fixes
- HUD not stretched anymore
- Crosshair match hit point
- perspective adjusted

Install
Extract into vice city directory. Enable the widescreen option in the display menu. Be sure to keep the file in the directory only if you're playing in widescreen. Otherwise it will affect 4:3 displays.

[[CTD]LaBan]

Great! Now i can play correctly on my laptop, too

Nice!! But.... any release for SA??

[Alexander Blade]

N1ce fix !
may be if Squiddy will tell me how he did it for VC i'll do this 4 SA

[Squiddy]

Thank you all.

Does SA really have the same problems? I am surprised, I expected them to handle this better. Of course I do my best to help you Alexander, you might want to check the source, it really is not much I did, research lasted longer than everything else:
http://squiddy.marway.org/gta/source/vcwidescreen.txt

But if you don't work with VC it probably doesn't help you much, maybe I can explain it better.

First priority was to fix the crosshair position, which is drawn in CHud::Draw. The calculation used some floats for scaling. As I changed them, the bullet hit position was changed too, so I had to change the code and manually adjusted them to fit.

CODE

float shoot_scale_x = 0.5362989902f; float shoot_scale_y = 0.3810000122f; DWORD p = vcversion::AdjustOffset(0x5575FA); VirtualProtect((void*)p, 4, PAGE_EXECUTE_READWRITE, &dwProt); *(DWORD*)p = (DWORD)&shoot_scale_x; VirtualProtect((void*)p, 4, dwProt, &dwProt); p = vcversion::AdjustOffset(0x55760A); VirtualProtect((void*)p, 4, PAGE_EXECUTE_READWRITE, &dwProt); *(DWORD*)p = (DWORD)&shoot_scale_y; VirtualProtect((void*)p, 4, dwProt, &dwProt);

Second was the vertical scale of the whole display. Strechnutter had that option in VC Camhack, called 'Height stretch'. Maybe it's present in SA too. This value is changed when activating cutscenes for example.

CODE

p = vcversion::AdjustOffset(0x54A29E); VirtualProtect((void*)p, 4, PAGE_EXECUTE_READWRITE, &dwProt); *(float*)p = 1.56f; VirtualProtect((void*)p, 4, dwProt, &dwProt);

The horizontal scaling of the HUD was corrected. Everything was affected, excepts the radar map sprites. They had to be adjusted seperatly.

CODE

*(float*)vcversion::AdjustOffset(0x697A70) = hud_scale_x; *(float*)vcversion::AdjustOffset(0x68FD14) = radar_scale_x;

When I corrected the huds horizontal scale, the sniper mode had a bug. The black rectangles left and right to the sniper texture had to be made wider, otherwise a small coloumn was not black. This is how it looked in the end:

Well, I hope this helps you somehow.
If there is any question, feel free to ask.

San Andreas on my PC always looks all stretched upwards. I've resorted to the CamHack, it fixes the problem. I haven't noticed any aiming difficulties though, but I'll be glad if you can fix this. It just eliminates another app I keep open when gaming.

2Squiddy : thx a lot )

[simkas]

I f*cking love you.

[simkas]

I'm having a problem with this. When I put the .asi in my game foler, the screen looks more stretched in widescreen mode.

[Squiddy]

Did you enable the widescreen option in the display settings? It is needed, as the mod is correcting the settings done by VC. If this doesn't help, could you post a screenshot?

[simkas]

Here's how it looks without this fix:

And here's what it is with the fix:


With the fix, the hud doesn't look so stretched, but the view is stretched down verticaly.

[Squiddy]

Well... that's going to be difficult. Thing is, I asked a friend what vertical scale he prefers, that's the one I chose for the fix. It's really a matter of personal taste I assume, but imo on the second screenshot Tommy does look more natural than on the other one.
If you prefer a different setting, I need to make it configurable.

He looks too short in the second picture.

[Squiddy]

Well, yeah. I guess I can find 10 people claiming he is too tall in the first picture.

Okay, I make it configurable then, maybe today, maybe tomorrow.

[spaceeinstein]

I don't know if other people have this issue but someone posted this problem with the widescreen fix.

Oh, never checked that.

Makes sense, because that map is rendered in the same function as the HUD I think. When I corrected the scale factor for the hud, the icons position stayed the same. Two possibilities.. stretching the map in that display or correcting the icons position. I think the first is easier. I'll check that out.

Edit
Okay, figured out where the problem is, just need to find a good way to fix it. Maybe I do it the lazy way, at least the bug will be fixed then.

Thanks man, I really needed this. Good job. Correct me if I'm wrong, but I think you just made the aiming circle at the location of where the Widescreen mode fires, instead of changing the line of fire location to where the aiming circle is. Yes?

[Squiddy]

Yes, I found this to be the easiest solution and I think it doesn't really makes a difference in playing, does it?

[The Kirbster]

No, I find it easier to use sometimes . Great job on the mod, and good luck with fixing the map glitch.
